It contains an integrated Root Hub with two USB ports, PCI interface, and USB Host Controller.
  • Page 279: Function Description

    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.
  • Page 280: 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.
  • Page 281 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.
  • Page 282 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 .
  • Page 283: Figure 18.2 List Priority Within A Usb Frame

    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.
  • Page 284: Figure 18-3. Example Of Control/bulk Service Ratio Of 4:1

    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.
  • Page 285 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.
  • Page 286 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.

  • Page 294: Table 18.1 Example Calculation Of R And Host Controller Action

    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.
  • Page 295: Table 18.2 Itd Packet Offset Location

    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.
  • Page 296 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.
  • Page 297 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.

    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).
  • Page 305 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.
  • Page 306 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).
  • Page 307 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.
  • Page 308 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: •...
  • Page 309 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.
  • Page 310 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.
  • Page 311 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 312: Usb Interface

    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.
  • Page 313: Table 18.13 Transaction Control Information

    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.
  • Page 317: Figure 18.12 Preamble Packet Format

    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.
  • Page 318: Figure 18.13 Serializer

    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.
  • Page 319: Figure 18.14 Crc Logic

    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.
  • Page 320 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).
  • Page 321 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.
  • Page 322 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.

    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.
  • Page 326 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.

    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.
  • Page 330: Table 18.21 Power Switching Configurations

    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.
  • Page 331 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.
  • Page 332 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.
  • Page 333 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.

    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.
  • Page 356: A/d Control/status Register (adcsr)

    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.
  • Page 357: A/d Calibration Sample Control Register (adcalcr)

    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.
  • Page 358: Operation

    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.

  • Page 360: Scan Mode (scan = 1)

    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.
