CPU INTERFACE Module builds an internal peripheral bus interface on HD64465. This interface provides a bridge between Hitachi SH-3/SH-4 CPU and all peripheral modules in HD64465. This section will explain the functionality and timing of all signals defined in CPU interface module.
CPU Interface Signal Description 5.2.1 System Bus Interface Signals In system bus interface, the configuration of BSC in SH-4/SH-3 needs to be programmed properly. The followings list the bus configuration requirements. 1. Area: Area 4 2. Bus width: Longword (32 bits) size and little endian access. 3.
5.2.2 Internal Bus Interface Signals Signal Name I/O Type Description Internal Module Reset: This signal is module reset of *module. (For example, *RESET# LCDC reset signal is LCDC_RESET#) *STBY Module Standby: This signal is used to control the standby mode for each peripheral module.
Function Description CPU Interface Module is a bridge between the CPU bus and all peripheral modules in HD64465. This interface module handles the command, address and data transaction between CPU and HD64465 modules. The diagram of Figure 5-1 illustrates how the interface signals are connected.
5.4.1 Low Speed Timing HD64465 provides a programmable bit (SLS) in System Configuration Register (SCONFR) to increase the system performance, depending on different bus clock (CKIO) rates. When SLS bit is programmed with 1, the internal bus timing is switched to the basic cycle composed of two wait states.
Low-Speed Internal Bus Access Timing with TWe phase is shown in the Figure 5-3. The diagram shows the cycles are T1, TWs1, TWs2, TWe and T2 phases. Note that there are two wait states and one external peripheral hardware wait state in command cycle. In this case, the basic command cycle is not enough for peripheral operation, it is responsible for the peripheral module to insert its own wait signal before T2 stage.
With the programmable bit (SLS) contained in System Configuration Register (SCONFR), the HD64465 is able to increase the system performance, depending on different bus clock (CKIO) rates. When SLS bit is programmed with 0, the internal bus timing is switched to the basic cycle composed of three wait states.
High-Speed Internal Bus Access Timing with TWe phase is shown in the Figure 5-5. The diagram shows the cycles are T1, TWs1, TWs2, TWs3, TWe and T2 phases. Note that there are three wait states and one peripheral hardware wait state in command cycle. In this case, the basic command cycle is insufficient for peripheral operation.
Internal Bus Data Swap Rules Internal Bus Data Swap Rules are defined to satisfy the legacy peripheral modules. This is because the data bus width has been changed from 16 bits to 32 bits. For the compliance with these legacy peripheral modules, it is required to establish a data swap mechanism described below: Case 1: Word Access (16 bits) IMADDR=0 CPU Bus...

Standby mode, Bus gating, Wait states, Peripheral Clock Control, Module Software Reset and Test Mode. Each module in the HD64465 is provided with the STANDBY mode. All peripheral module functions are halted in the STANDBY mode; thereby reducing the power consumption. The Bus gating control is used with STANDBY mode for further power saving capability The Hardware external wait cycle inserted by CPU interface module is an option to extend data read/write cycles.
Register Description The following table lists all the registers. The unit of the register size and access size is byte. The register size is the actual size of registers. The access size defines the data bus width of host CPU, which is used to access each register.
System Module Standby Control Register (SMSCR) [cont’d] Description Default Reserved. PS2ST: PS2 Standby. When this bit is set, the PS2 will enter the standby mode until this bit is cleared. The PS2 will be in normal operation mode after this bit is cleared. This bit is set after reset.
6.3.2 System Configuration Register (SCONFR) This register provides a flexible approach for system configuration. The hardware wait insertion control is flexible to control CPU interface command cycle. Parallel Port function select can also be programmed by this register. The detailed functionality, which can be configured, is described below: Address: H'10000002 Bit Name...
System Configuration Register (SCONFR) [cont’d] Description Default USBCKS: USB Host interface Clock Switch. When this bit is cleared, USB Host interface clock will be the clock output from PLL1. When this bit is set, the USB Host interface clock will be the half frequency of CKIO. SCDICKS: Serial Codec Interface Clock Switch.
System Bus Control Register (SBCR) [cont’d] Description Default PDOF: Port D Output Floating Control. When this bit is set, the output will be floating. When this bit is cleared, the output floating is disabled. PDIG: Port D Input Gating Control. When this bit is set, the input to port D will be gated to fixed value.
6.3.4 System Peripheral Clock Control Register (SPCCR) This register provides the function of peripheral clock control for each peripheral module. When the peripheral module is in standby mode, the peripheral clock can be turned off to reduce more power consumption, thanks to the free running of the peripheral clock. To stop the peripheral clock, the peripheral module standby mode must be asserted first.
System Peripheral Clock Control Register (SPCCR) [cont’d] Description Default FIRCLK: FIR Controller Clock Control. When this bit is set, the FIR clock will be halted. The FIR clock will run normally after this bit is cleared. Note that this bit can be cleared only Twkst ms later, the UCKOSC bit has already been cleared.
Peripheral Clock Relationship Diagrams shows the working relationship among the clock source and generated peripheral clocks. It also indicates the sequence of turning off one peripheral clock without interfering the other peripheral clocks operation. For example, in Figure 6-1, If the bit AFEOSC is set, then peripheral clocks like AFE_clk and SCDI_clk will be halted because the source clock AFECK is halted.
6.3.5 System Peripheral S/W Reset Control Register (SPSRCR) The software reset of each peripheral module is an option when the peripheral module encounters functional failures after clearing the STANDBY mode of the module. These software reset bits need the clock from UCK oscillator to count the reset period, which means that the UCKOSC bit needs to be cleared first before setting these reset bits.
System Peripheral S/W Reset Control Register (SPSRCR) [cont’d] Description Default PPSRT: Parallel Port Controller Software Reset. When this bit is set, the parallel port controller will be reset. This reset is equivalent to hardware reset. All the parallel port registers are set to the reset default values. Note that the software reset bit is self- clearing.
6.3.6 System PLL Control Register (SPLLCR) This register provides the PLL control options. Address: H'1000000A Bit Name Initial Value Bit Name PLL2SB PLL1SB - PLL2BP PLL1BP Initial Value Description Default 15 - 6 Reserved. PLL2SB: PLL2 Standby control. When this bit is set, the PLL2 standby mode is enabled. When this bit is cleared, the PLL2 standby mode is disabled.
6.3.7 System Revision Register (SRR) This register records the revision number of the controller, which is read only. The revision number is presented with mj.mi. The mj[7:0] stands for the major change number and its value is the content of the register’s high byte. The mi[7:0] stands for the minor change number, and its value is the content of the register’s low byte.
HD64465 provides the system hardware reset function to control SH-4/SH-3 CPU power-on reset or manual reset. In Figure 6-3, it shows that two input signals on HD64465, RESETMI# and RESETPI#, which control the manual reset and power-on reset respectively. The other signals, RESETPO# and RESETMO#, are the output signals connected to SH-4/SH-3 CPU for power-on reset and manual reset.
When RESETMI# is asserted, it means the manual reset is occurred. The manual reset signal from HD64465, RESETMO#, is connected to CPU manual reset input. For SH-4 and SH-3 CPU, the manual reset mechanism is different. Figure 6-5 shows the manual reset timing for SH-4 CPU and Figure 6-6 shows the manual reset timing for SH-3 CPU.
Section 7 General Purpose I/O Port Overview The HD64465 incorporates five general purpose 8-bit I/O ports (Port A, Port B , Port C, Port D and Port E ). As shown in the Table 7-1 below, the port pins are multiplexed with other functions, which are controlled by Port Control Registers (GPxCR x: A,B,C,D,E).

Section 8 Interrupt Controller (INTC) Overview The Intelligent Peripheral Controller interrupts are issued from the modules of PS/2, PCMCIA, AFE, GPIO port, Timer, Keyboard Controller, IrDA , UART, PP, SCDI, USB, and ADC. The controller contains a register for the interrupt request status issued from each module. After SH-4/SH7709 detects the interrupt, it reads the interrupt request register to see which module generates the interrupt, and then reads the interrupt request register in each module.
Interrupt Sources 8.2.1 On-Chip Module Interrupt Interrupt sources are derived from on-chip peripheral module Interrupts. Each interrupt provides a mask bit in each module listed below: • PS/2 Keyboard • PS/2 Mouse • PCMCIA Controller (PCC) • Analog Front End (AFE) Interface •...

Host determines whether peripheral supports ECP protocol during the process. After the negotiation is completed, the mode is set to 011 (ECP). To enable the drivers, direction must be set to “0”.

Section 18 USB Host Controller 18.1 Introduction 18.1.1 Device Description / Purpose This USB Host Controller is a PCI-based implementation of the Universal Serial Bus (USB) 1.0 specification utilizing the OpenHCI standard developed by Compaq, Microsoft, and National Semiconductor. It contains an integrated Root Hub with two USB ports, PCI interface, and USB Host Controller.
The following diagram shows the whole system architecture, which relates the Host CPU(Hitachi SH4 CPU) and HD64465 USB Host Controller by built-in Host/PCI bridge and SRAM Controller. It means that the internal SRAM memory space is the communication channel between Host CPU and USB Host Controller.
18.2.2 USB Host Controller USB States The Host Controller has four USB states visible to the Host Controller Driver via the Operational Registers: U , and U . These states define the PERATIONAL ESET USPEND ESUME Host Controller responsibilities relating to USB signaling and bus states. The USB states are reflected in the HostControllerFunctionalState field of the HcControl register.
USB OPERATIONAL When in the U state, the Host Controller may process lists and will generate SOF PERATIONAL Tokens. The U state may be entered from the U or U states. It PERATIONAL ESUME ESET may be exited to the U or U states.
USB RESUME When in the U state, the Host Controller forces resume signaling on the bus. While in ESUME , the Root Hub is responsible for propagating the USB Resume signal to downstream ESUME ports as specified in the USB Specification. The Host Controller's list processing and SOF Token generation are disabled while in U .
List Control Block 1) Priority The list priorities are modified as endpoints are serviced and at periodic intervals. In each frame, an interval of time is reserved for processing of items in the Control and Bulk lists. This interval is at the beginning of each frame. The Host Controller Driver limits this time by writing HcPeriodicStart with a bit time after which periodic transfers (Interrupt and Isochronous) have priority for use of the bus.
a) List Priority The lists built up by the Host Controller Driver are classified as either periodic or non- periodic. The Interrupt list and the Isochronous list are periodic because the endpoints on those lists require service at specific times in a deterministic manner. The Control list and the Bulk list are non-periodic because endpoints on those lists can tolerate latency and expect service only on a time-available basis.
The Host Controller enforces the Control Bulk Service Ratio regardless of the number of Control and Bulk Endpoint Descriptors present on their respective lists. If there is only 1 CTRL ED (Control Endpoint Descriptor) on the Control list and the Control Bulk Ratio is 4:1, that CTRL ED is serviced 4 times before a BULK ED (Bulk Endpoint Descriptor) is serviced.
ED Block The ED Block is responsible for processing Endpoint Descriptors. This includes reading EDs from memory, servicing an active TD if necessary, and writing back information if necessary. 1) List Service Flow This section describes the actions required of the Host Controller during list processing. These actions are taken after the Host Controller has determined which particular list is to be serviced.
SERVICE LIST List Read Peridoc List? FINISHED Enabled? HEAD pointer HEAD pointer Hc _ _ _ _ CurrentED = 0? = 0? _ _ _ _Filled = 1? Hc _ _ _ _ CurrentED = (Bulk or Control) Hc _ _ _ _ HeadED _ _ _ _Filled = 0 ISOCHRONOUS Hc_ _ _ _CurrentED =...
Locating Endpoint Descriptors After determining a list is enabled, the Host Controller locates the first Endpoint Descriptor requiring service. The first time the Host Controller services a list after entering the state, it uses the lists Head Pointer to locate the first Endpoint Descriptor PERATIONAL on the list.
3. If the current list is the Control List, the Host Controller next action is dependent on whether or not the number of Control Endpoint Descriptors dictated by the Control/Bulk Service Ratio have been serviced. If the Control/Bulk Service Ratio has been satisfied, the Host Controller moves on to the Bulk list;...
2) Endpoint Description Processing During the processing of a list, the Host Controller is required to interpret and service the Endpoint Descriptors present on that list. The flow for service of an Endpoint Descriptor is shown in Figure 18-5. SERVICE ENDPOINT DESCRIPTOR HALT = 1...
Transfer Description Priority The priority of Transfer Descriptors on a queue is first-come-first-serve. The Transfer Descriptors the Host Controller services are always part of a queue attached to an Endpoint Descriptor. The Host Controller services the first Transfer Descriptor on the queue which is pointed to by the NextTransferDescriptor field of the Endpoint Descriptor.
5) Description Registers The ED Block maintains 4 32-bit registers to hold requested Endpoint Descriptors. These registers are used as temporary storage for Endpoint Descriptors being serviced and are not addressable by software. Figure 18-6 shows the fields present in each of the 4 Endpoint Descriptor registers.
1) Transfer Description Processing Transfer Descriptor processing is the fundamental operation performed by a Host Controller. The service flow for servicing a Transfer Descriptor is shown in Figure 18-7 below. The rest of this section describes the steps necessary for completing service of a Transfer Descriptor. SERVICE TRANSFER DESCRIPTOR...
a) Isochronous Relative Frame Number Calculation When processing an Isochronous Transfer Descriptor, the Host Controller must calculate the relative frame number. This calculation determines which, if any, packet will be sent during the current frame. An Isochronous TD may contain buffers for 1 to 8 consecutive frames of data (FrameCount+1) with the first (0th) data packet of an Isochronous TD sent in the frame for which FrameNumber match the StartingFrame field of the Isochronous TD.
b) Isochronous Packet Begin and End Address Calculation When processing an Isochronous Transfer Descriptor, the RelativeFrame (R) is used to select two offset values, BeginAddrOffset and EndAddrOffset. EndAddrOffset is the lower 12 bits of the last byte of the packet +1. The source of these offsets is shown in Table 18-2. Refer to next section for a description of the Descriptor Registers used.
d) General Packet Begin and End Address Calculation When the Host Controller fetches a General Transfer Descriptor, it gets the address of the next memory location to be accessed from CurrentBufferPage and CurrentBufferOffset. If these values are both 0, then the packet size will be zero, regardless of the setting of MaximumPacketSize in the Endpoint Descriptor.
If the CurrentBufferPointer requires an update and is not the last packet, the number of bytes transmitted in the packet should be added to the current value of the CurrentBufferPointer field. If the packet crossed a page boundary, the upper 20 bits of the CurrentBufferPointer should be updated with the BufferEndPage field to reflect the change in page base address.

g) Transfer Description Retirement When a transfer descriptor is complete (all data sent/received), the ErrorCount reaches 3 for a GTD, a fatal error condition occurs for a GTD, or an ITD is late, the Transfer Descriptor must be retired. A fatal error is classified as the new CompletionCodes of Stall, DataOverrun, DataUnderrun, and UnexpectedPID.
h) Done Queue Occasionally (as determined by the Done Queue Interrupt Counter = 0), when the Done Queue contains one or more Transfer Descriptors, the Host Controller writes the current value of HcDoneHead into the HccaDoneHead immediately following a frame boundary and generates an interrupt.
a) Dword0 Dword0 contains the status information for the Transfer Descriptor. • Field Table 18.4 Dword0 GTD Fields Bit Range Field 31 - 28 CompletionCode 27 - 26 ErrorCount 25 - 24 DataToggle 23 - 21 DelayInterrupt 20 - 19 Direction BufferRounding Table 18.5 Dword0 ITD Fields...

BEOffset is the buffer end address +1. Offset1 is used for ITDs under certain circumstances to store begin address of the next packet. • Load Condition There are two load conditions for Dword3. The first condition occurs for every TD that is loaded.
Request Block The system request portion of the List Processor is the top level coordinator of all activity. It arbitrates the master requests, multiplexes the data and control signals to the Host Controller Bus Master. 1) Master Arbitration There are three sources of master requests from the List Processor: HCCA Writeback request (HCCAWBReq), ED request (EDReq), and TD request (TDReq).
Frame Management The frame management block is responsible for managing the frame specific tasks required by the USB specification and the OpenHCI specification. These tasks are: 1. Management of the OpenHCI frame specific Operational Registers 2. Operation of the Largest Data Packet Counter 3.
The FrameRemainingToggle field (bit) is loaded with FrameIntervalToggle coinciding with FrameRemaining being loaded with FrameInterval. FrameRemainingToggle and FrameIntervalToggle are used by the HCD to determine which value of FrameInterval is being used in the current frame. If the toggle fields match when read, the Host Controller loaded the current value of FrameInterval into FrameRemaining at the beginning of the current frame (current frame is using a newly programmed value).
Packet Size Check When a TD is loaded, the packet size must be guaranteed to complete within the remaining frame time. The sections below discuss FS and LS transaction frame requirements. 1) Full speed Check The full speed packet size check is accomplished by comparing the value of a data transactions data packet size (in bits) with the current value of the Largest Data Packet Counter.
Interrupt Processing Interrupts are the communication method for HC-initiated communication with the Host Controller Driver. There are several events which may trigger an interrupt from the Host Controller. Each specific event sets a specific bit in the HcInterruptStatus register. The Host Controller requests an interrupt when all three of the following conditions are met: •...
ResumeDetected Event A resume detected event occurs when the Root Hub detects resume signaling on the USB bus. The Host Controller will set the ResumeDetected bit when resume signaling is detected. A ResumeDetected interrupt is only possible in the U state.
OwnershipChange Event The OwnershipChange bit is set by the Host Controller when the Host Controller Driver sets the OwnershipChangeRequest bit in the HcCommandStatus register. This ensures that an interrupt is generated (unless it is masked) whenever ownership of the Host Controller is passed to and from the operating system Host Controller Driver and any SMM-based Host Controller Driver in the system.
The Bus Master Controller maintains the address of the next PCI cycle to be requested. The address is initialized with a value from the List Processor when it initiates a request. The address is updated after each burst transfer completes. This is needed for data transfers that require more than a single burst cycle.
Page Crossing Controller The Page Crossing Controller is responsible for controlling the page address of data transfers. If it receives a request from the Data Buffer Engine that crosses a page boundary, it will break up the request into two separate requests to the Bus Master Controller. The first request will contain the data from the first page, the second request will contain the data from the second page.
Serial Interface Engine (SIE) The SIE is responsible for managing all transactions to the USB. It controls the bus protocol, packet generation/extraction, data parallel-to-serial conversion, CRC coding, bit stuffing, and NRZI encoding. All transactions on the USB are requested by the List Processor and Frame Manager. After the List Processor retrieves all information necessary to initiate communication to a USB device, it generates a request to the SIE accompanied by endpoint specific control information required to generate proper protocol and packet formats to establish the desired communication pipe.
2) End of Packet (EOP) Every packet is terminated by an end of packet (EOP) consisting of 2 transmitted single-ended zeros (SE0) followed by a driven idle state for another bit time. 3) Packet Identifier (PID) Each packet contains a packet identifier (PID) declaring the packet function. The PID is transmitted as a 4-bit encoding followed by the bitwise inversion of the PID as an error check.
5) Data Packet The data packet contains the actual data transfer between the host and endpoint specified in the token packet. DATA0 and DATA1 identify the packet as a data packet. The 0/1 tag on the PID provides a mechanism for data synchronization from one data packet to the next to the same endpoint.
7) Preamble Packet The preamble packet is used to inform downstream hubs that a low speed packet is coming. This allows the low speed drivers to be enabled by all ports connected to low speed devices. This is repeated for all packets within the transaction and not just preceding the token packet. This procedure applies only to packets from the host and not packets received from the device.
Serializer The Serializer performs the parallel/serial conversion for both transmitting and receiving. The logic consists of a packet control state machine, 8-bit parallel-load/serial-shift register, 8-bit data latch, PID encoder/decoder, CRC generator/checker, bit stuff counter, NRZI encoder, and data receiver circuit. Data paths of transmitted and received paths share logic since the bus only operates one direction at a time and the path's logical organizations are simply reversed.
1) Data Data fields of the token packets are provided by the List Processor and Frame Manager. For a transmitted data packet, the Data Buffer Engine provides the data. Each time a byte is loaded into the shifter the buffer pointer is incremented. The data buffer marks the data byte enabling the CRC remainder into the data stream.
1. Token - All data following the PIDs are included in the CRC generation. Equation 18-1 is the polynomial used to generate the token packet CRC: G(X) = X 5 + X 2 + 1 = 10101b Equation 18.1 Token Packet CRC Generator Polynomial After the token data is finished the source of the transmitted bit stream is switched to the CRC (MSb first).
3) Bit Stuffing A data rate phase lock requires frequent bus transitions to maintain the lock before the drift potential threaten to corrupt the data stream. To guarantee transitions occur before the data rate drifts to far to maintain the phase lock, bit stuffing is employed to force transitions after 6 bit times without a transition.
The phase lock function is required regardless of the data rate, FS or LS, though timing requirements differ. EOP A valid EOP is identified by the receiver by sampling a SE0 for three consecutive 48 MHz clock periods following by a J-state. This allows for an approximate minimum SE0 pulse width of 40 ns.
Bus Protocol 1) Non-Isochronous Transactions Figure 18-15 shows the valid packet sequencing of a non-isochronous transfer. From From IDLE Host Device LS = Low Speed Transaction Token SETUP Data DATA DATA Handshake STALL Figure 18.15 Non-Isochronous Bus Transaction Rev. 3.0, 03/01, page 304 of 390...
2) Isochronous Transfers Figure 18-16 shows the valid packet sequence of an isochronous transfer. An isochronous transfer is characterized by the lack of a handshake phase after a data phase. Note that a handshake is still permitted following the token phase, if a handshake condition is present which supersedes the data phase.
a) Back to Back Host Packets During back to back host packets of the same transaction (e.g. token to data packet), a minimum of 2 idle bit times are required from the end of the EOP's SE0 to the SOP of the next packet.
5) Data Toggle Synchronization The data toggle PIDs, DATA0 and DATA1, are the final check to ensure the device received a valid ACK handshake. The data packet receiver is responsible for maintaining data toggle bit synchronization. Therefore, the HC is required to correct the IN data toggle synchronization only, while the device corrects OUT data synchronization.
When a transaction completes, the completion status is reported to the List Processor. The SIE can compile all error information to create the CompletionCode field for the TD writeback, but may be overridden by the List Processor. Table 18-17 shows the transaction status (nearly identical to the CompletionCode) definitions generated by the SIE to the List Processor.
Root Hub The Root Hub is a collection of ports which are individually controlled and a hub which maintains control/status over functions common to all ports. The typical command request interface to the hub is emulated by the HCD which communicates directly through the system bus (PCI) to the hub and port controls.
Hub Control The HC states defined in HC Register Summary section also reflect the hub state. For example, when the HC is suspended, U , the Root Hub is suspended. When the HC is in USPEND , the hub generates the appropriate bus signaling. U resets the Root Hub.
5) Resume When the HC is in U , the resume signal, K-state, is broadcast to all enabled ports, ESUME but not selectively suspended ports. Signaling is maintained until the HC leaves U ESUME A trailing LS EOP is used to terminate the resume. After the Resume is removed, bus activity returns to normal.
If DeviceRemoveable is set for the port, which means not removable (yes, it is backwards), CurrentConnectStatus is always read a ‘1’. After power is enabled to the port or a hardware reset when no power switching is implemented, a connect event will be detected through the previously defined method resulting in ConnectStatusChange being set and LowSpeedDeviceAttached being configured.
If the hub is suspended, i.e. U , while the port is also suspended, the port does not USPEND respond to a U transition. However, an upstream resume at the port forces a ESUME transition. ESUME Interrupts A Root Hub interrupt, RootHubStatusChange, is generated by setting any of the XXXXChange fields in the HcRhStatus and HcRhPortStatus registers.
18.2.4 Power Management At this time, USB Host Controller supports minimal system level power management features. Each system has its own requirements which makes it impossible to satisfy. The only power management feature implemented is the disabling of the USB clock generator in U USPEND state.
18.2.5 Register/Address Summary OpenHCI Registers Although USB Host Controller has a PCI interface, however the configuration cycle is not needed to perform on it. From the point of view of CPU, the access of these registers is transparent just like the memory access. The base address of HC registers is 0x1000B000.

19.2 Register Descriptions 19.2.1 A/D Data Registers A to D (ADDRA to ADDRD, ADCAL) The five A/D data registers (ADDRA to ADDRD, ADCAL) are 16-bit read-only registers that store the results of A/D conversion. An A/D conversion produces 10-bit data, which is transferred for storage into the A/D data register in correspondence to the selected channel.
19.2.2 A/D Control/Status Register (ADCSR) ADCSR is a 16-bit readable/writable register that selects the mode and controls the A/D converter. ADCSR is initialized to H’0000 by a reset and is in STANDBY mode. Bit Name ADF* ADST ADIS* TRGE ADIE SCAN Initial Value *NOTE: Only 0 can be written to clear the flag bits.
19.2.3 A/D Calibration Sample Control Register (ADCALCR) ADCALCR is a 16-bit write-only register that enables A/D calibration sample conversion. When the calibration sample is enabled, the A/D conversion produces 10-bit data which corresponds to the calibration analog value (½ VDD = ½ x 3.3 Volt). The 10-bit data will be stored into ADCAL register.
19.3 Operation The A/D converter operates by successive approximations with 10-bit resolution. It has two operating modes: single mode and scan mode. 19.3.1 Single Mode (SCAN = 0) Single mode should be selected when only one A/D conversion in one channel is required. The A/D conversion starts when the ADST bit is set to 1 by software, or by external trigger input.

19.3.2 Scan Mode (SCAN = 1) Scan mode is useful for monitoring analog inputs of one or more channels. When the ADST bit is set to 1 by software or external trigger input, A/D conversion starts on the first channel (AN0). When two or more channels are selected, the conversion of the second channel (AN1) starts immediately after the first channel finishes the conversion.
19.3.3 Input Sampling and A/D Conversion Time The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog input at a time t after the ADST bit is set to 1, then starts the conversion. Figure 19-4 shows the A/D conversion timing.

When the TRGE bit is set to 1 in ADCR, the external trigger input is enabled by TMOUT#.
19.5 Usage Notes When using the A/D converter, note the following points: Analog Input Voltage Range: During A/D conversion, the voltages input to the analog input pins ANn should be in the range 0 ≤ ANn ≤ 3.3V. (n = 0 to 3) AVcc and AVss Input Voltages: AVss should have the following value: AVss = Vss.

When the HD64465 sets the CLOCK line low before the falling edge of the tenth clock it indicates that a complete byte has been received. The mouse sees this as a host request to abort the byte being transmitted. When the host allows the CLOCK line to go high the mouse will send the aborted byte again.
