Section 2 CPU Overview The H8/300L CPU has sixteen 8-bit general registers, which can also be paired as eight 16-bit registers. Its concise instruction set is designed for high-speed operation. 2.1.1 Features Features of the H8/300L CPU are listed below. •...
2.1.2 Address Space The H8/300L CPU supports an address space of up to 64 Kbytes for storing program code and data. See section 2.8, Memory Map, for details of the memory map. 2.1.3 Register Configuration Figure 2.1 shows the register structure of the H8/300L CPU. There are two groups of registers: the general registers and control registers.
Register Descriptions 2.2.1 General Registers All the general registers can be used as both data registers and address registers. When used as data registers, they can be accessed as 16-bit registers (R0 to R7), or the high bytes (R0H to R7H) and low bytes (R0L to R7L) can be accessed separately as 8-bit registers. When used as address registers, the general registers are accessed as 16-bit registers (R0 to R7).
Page 58
Condition Code Register (CCR) This 8-bit register contains internal status information, including the interrupt mask bit (I) and half-carry (H), negative (N), zero (Z), overflow (V), and carry (C) flags. These bits can be read and written by software (using the LDC, STC, ANDC, ORC, and XORC instructions). The N, Z, V, and C flags are used as branching conditions for conditional branching (Bcc) instructions.
2.2.3 Initial Register Values When the CPU is reset, the program counter (PC) is initialized to the value stored at address H'0000 in the vector table, and the I bit in the CCR is set to 1. The other CCR bits and the general registers are not initialized.
2.3.1 Data Formats in General Registers Data of all the sizes above can be stored in general registers as shown in figure 2.3. Data Type Register No. Data Format 1-bit data Don't care 1-bit data Don't care Byte data Don't care Byte data Don't care Word data...
2.3.2 Memory Data Formats Figure 2.4 indicates the data formats in memory. The H8/300L CPU can access word data stored in memory (MOV.W instruction), but the word data must always begin at an even address. If word data starting at an odd address is accessed, the least significant bit of the address is regarded as 0, and the word data starting at the preceding address is accessed.
Addressing Modes 2.4.1 Addressing Modes The H8/300L CPU supports the eight addressing modes listed in table 2.1. Each instruction uses a subset of these addressing modes. Table 2.1 Addressing Modes Address Modes Symbol Register direct Register indirect Register indirect with displacement @(d:16, Rn) Register indirect with post-increment @Rn+...
Page 63
Register Indirect with Post-Increment or Pre-Decrement—@Rn+ or @–Rn: • Register indirect with post-increment—@Rn+ The @Rn+ mode is used with MOV instructions that load registers from memory. The register field of the instruction specifies a 16-bit general register containing the address of the operand.
The upper 8 bits of the absolute address are assumed to be 0 (H'00), so the address range is from H'0000 to H'00FF (0 to 255). Note that with the H8/300L Series, the lower end of the address area is also used as a vector area. See section 3.3, Interrupts, for details on the vector area. If an odd address is specified as a branch destination or as the operand address of a MOV.W instruction, the least significant bit is regarded as 0, causing word access to be performed at the address preceding the specified address.
Instruction Set The H8/300L Series can use a total of 55 instructions, which are grouped by function in table 2.3. Table 2.3 Instruction Set Function Instructions Number MOV, PUSH * , POP * Data transfer Arithmetic operations ADD, SUB, ADDX, SUBX, INC, DEC, ADDS, SUBS, DAA, DAS, MULXU, DIVXU, CMP, NEG Logic operations AND, OR, XOR, NOT...

Basic Operational Timing CPU operation is synchronized by a system clock (φ) or a subclock (φ ). For details on these clock signals see section 4, Clock Pulse Generators. The period from a rising edge of φ or φ the next rising edge is called one state. A bus cycle consists of two states or three states. The cycle differs depending on whether access is to on-chip memory or to on-chip peripheral modules.
2.6.2 Access to On-Chip Peripheral Modules On-chip peripheral modules are accessed in two states or three states. The data bus width is 8 bits, so access is by byte size only. This means that for accessing word data, two instructions must be used.

CPU States 2.7.1 Overview There are four CPU states: the reset state, program execution state, program halt state, and exception-handling state. The program execution state includes active (high-speed or medium- speed) mode and subactive mode. In the program halt state there are a sleep (high-speed or medium-speed) mode, standby mode, watch mode, and sub-sleep mode.
Reset cleared Reset state Exception-handling state Reset occurs Reset Interrupt occurs source Reset Interrupt Exception- occurs occurs source handling occurs complete Program halt state Program execution state SLEEP instruction executed Figure 2.15 State Transitions 2.7.2 Program Execution State In the program execution state the CPU executes program instructions in sequence. There are three modes in this state, two active modes (high speed and medium speed) and one subactive mode.

2.9.2 Notes on Bit Manipulation The BSET, BCLR, BNOT, BST, and BIST instructions read one byte of data, modify the data, then write the data byte again. Special care is required when using these instructions in cases where two registers are assigned to the same address, in the case of registers that include write- only bits, and when the instruction accesses an I/O port.

Application Notes 3.4.1 Notes on Stack Area Use When word data is accessed in the LSI, the least significant bit of the address is regarded as 0. Access to the stack always takes place in word size, so the stack pointer (SP: R7) should never indicate an odd address.
3.4.2 Notes on Rewriting Port Mode Registers When a port mode register is rewritten to switch the functions of external interrupt pins and when the value of ECPWME in AEGSR is rewritten to switch between selection/non-selection of IRQAEC, the following points should be observed. When an external interrupt pin function is switched by rewriting the port mode register that controls pins IRQ , IRQ...

Interrupt Request Flags Set to 1 Conditions When PMR5 bit WKP7 is changed from 0 to 1 while pin WKP IWPR IWPF7 is low and WEGR bit WKEGS7 = 0. When PMR5 bit WKP7 is changed from 1 to 0 while pin WKP is low and WEGR bit WKEGS7 = 1.
An alternative method is to avoid the setting of interrupt request flags when pin functions are switched by keeping the pins at the high level so that the conditions in table 3.5 do not occur. However, the procedure in Figure 3.7 is recommended because IECPWM is an internal signal and determining its value is complicated.

Prescalers The H8/38024 Group is equipped with two on-chip prescalers having different input clocks (prescaler S and prescaler W). Prescaler S is a 13-bit counter using the system clock (φ) as its input clock. Its prescaled outputs provide internal clock signals for on-chip peripheral modules.
Note on Oscillators Oscillator characteristics are closely related to board design and should be carefully evaluated by the user in mask ROM and ZTAT versions, referring to the examples shown in this section. Oscillator circuit constants will differ depending on the oscillator element, stray capacitance in its interconnecting circuit, and other factors.

Oscillator Stabilization Time after Standby Mode is Cleared Bits STS2 to STS0 in SYSCR1 should be set as follows. Note that stabilization times for the H8/38024, H8/38024S, and H8/38024F-ZTAT Group and for the H8/38124 Group are different. • When a oscillator is used The table below gives settings for various operating frequencies.
• When an external clock is used STS2 = 1, STS1 = 0, and STS0 = 1 should be set. Other values possible use, but CPU sometimes will start operation before wait time completion. • When the on-chip oscillator is used 8,192 states (STS2 = STS1 = STS0 = 0) is recommended if the on-chip oscillator is used on the H8/38124 Group.

Watch Mode 5.4.1 Transition to Watch Mode The system goes from active or subactive mode to watch mode when a SLEEP instruction is executed while the SSBY bit in SYSCR1 is set to 1 and bit TMA3 in TMA is set to 1. In watch mode, operation of on-chip peripheral modules is halted except for timer A, timer F, timer G, AEC and the LCD controller/driver (for which operation or halting can be set) is halted.
Subsleep Mode 5.5.1 Transition to Subsleep Mode The system goes from subactive mode to subsleep mode when a SLEEP instruction is executed while the SSBY bit in SYSCR1 is cleared to 0, LSON bit in SYSCR1 is set to 1, and TMA3 bit in TMA is set to 1.
Subactive Mode 5.6.1 Transition to Subactive Mode Subactive mode is entered from watch mode if a timer A, timer F, timer G, IRQ , or WKP interrupt is requested while the LSON bit in SYSCR1 is set to 1.

Direct Transfer 5.8.1 Overview of Direct Transfer The CPU can execute programs in three modes: active (high-speed) mode, active (medium-speed) mode, and subactive mode. A direct transfer is a transition among these three modes without the stopping of program execution. A direct transfer can be made by executing a SLEEP instruction while the DTON bit in SYSCR2 is set to 1.
• Direct transfer from subactive mode to active (medium-speed) mode When a SLEEP instruction is executed in subactive mode while the SSBY bit in SYSCR1 is set to 1, the LSON bit in SYSCR1 is cleared to 0, the MSON bit in SYSCR2 is set to 1, the DTON bit in SYSCR2 is set to 1, and the TMA3 bit in TMA is set to 1, a transition is made directly to active (medium-speed) mode via watch mode after the waiting time set in SYSCR1 bits STS2 to STS0 has elapsed.
Page 167
2. Time for direct transition from active (medium-speed) mode to active (high-speed) mode A direct transition from active (medium-speed) mode to active (high-speed) mode is performed by executing a SLEEP instruction in active (medium-speed) mode while bits SSBY and LSON are both cleared to 0 in SYSCR1, and bit MSON is cleared to 0 and bit DTON is set to 1 in SYSCR2.
4. Time for direct transition from subactive mode to active (medium-speed) mode A direct transition from subactive mode to active (medium-speed) mode is performed by executing a SLEEP instruction in subactive mode while bit SSBY is set to 1 and bit LSON is cleared to 0 in SYSCR1, bits MSON and DTON are both set to 1 in SYSCR2, and bit TMA3 is set to 1 in TMA.
Module Standby Mode 5.9.1 Setting Module Standby Mode Module standby mode is set for individual peripheral functions. All the on-chip peripheral modules can be placed in module standby mode. When a module enters module standby mode, the system clock supply to the module is stopped and operation of the module halts. This state is identical to standby mode.

) is 12.5 V. Use of a higher voltage can permanently damage the chip. Be especially careful with respect to PROM programmer overshoot. Setting the PROM programmer to Renesas (former Hitachi) specifications for the HN27C101 will result in correct V of 12.5 V.
If a series of programming errors occurs while the same PROM programmer is in use, stop programming and check the PROM programmer and socket adapter for defects. Please inform Renesas Technology of any abnormal conditions noted during or after programming or in screening of program data after high-temperature baking.
Flash Memory Overview 6.5.1 Features The features of the 32-Kbyte flash memory built into HD64F38024, HD64F38024R, and HD64F38124 are summarized below. • Programming/erase methods The flash memory is programmed 128 bytes at a time. Erase is performed in single-block units.
6.5.3 Block Configuration Figure 6.8 shows the block configuration of 32-Kbyte flash memory. The thick lines indicate erasing units, the narrow lines indicate programming units, and the values are addresses. The flash memory is divided into 1 Kbyte × 4 blocks and 28 Kbytes × 1 block. Erasing is performed in these units.
6.5.4 Register Configuration Table 6.5 lists the register configuration to control the flash memory when the built in flash memory is effective.

Descriptions of Registers of the Flash Memory 6.6.1 Flash Memory Control Register 1 (FLMCR1) — Initial value Read/Write — FLMCR1 is a register that makes the flash memory change to program mode, program-verify mode, erase mode, or erase-verify mode. For details on register setting, refer to section 6.8, Flash Memory Programming/Erasing.
Page 187
Bit 4—Program Setup (PSU) This bit is to prepare for changing to program mode. Set this bit to 1 before setting the P bit to 1 in FLMCR1 (do not set SWE, ESU, EV, PV, E, and P bits at the same time). Bit 4 Description The program setup state is cancelled...
Bit 0—Program (P) This bit is to set changing to or cancelling program mode (do not set SWE, ESU, PSU, EV, PV, and E bits at the same time). Bit 0 Description Program mode is cancelled (initial value) When this bit is set to 1, while the SWE = 1 and PSU = 1, the flash memory changes to program mode.
6.6.3 Erase Block Register (EBR) — — — Initial value Read/Write — — — EBR specifies the flash memory erase area block. EBR is initialized to H'00 when the SWE bit in FLMCR1 is 0. Do not set more than one bit at a time, as this will cause all the bits in EBR to be automatically cleared to 0.
Bit 7 PDWND Description When this bit is 0 and a transition is made to the subactive mode, the flash memory enters the power-down mode. (initial value) When this bit is 1, the flash memory remains in the normal mode even after a transition is made to the subactive mode.
On-Board Programming Modes There are two modes for programming/erasing of the flash memory; boot mode, which enables on- board programming/erasing, and programmer mode, in which programming/erasing is performed with a PROM programmer. On-board programming/erasing can also be performed in user program mode.
6.7.1 Boot Mode Table 6.8 shows the boot mode operations between reset end and branching to the programming control program. 1. When boot mode is used, the flash memory programming control program must be prepared in the host beforehand. Prepare a programming control program in accordance with the description in section 6.8, Flash Memory Programming/Erasing.

6.7.2 Programming/Erasing in User Program Mode The term user mode refers to the status when a user program is being executed. On-board programming/erasing of an individual flash memory block can also be performed in user program mode by branching to a user program/erase control program. The user must set branching conditions and provide on-board means of supplying programming data.
6.7.3 Notes on On-Board Programming 1. You must use the system clock oscillator when programming or erasing flash memory on the H8/38124 Group. The on-chip oscillator should not be used for programming or erasing flash memory. See section 4.2, On-Chip Oscillator Selection Method, for information on switching between the system clock oscillator and the on-chip oscillator.

4. Consecutively transfer 128 bytes of data in byte units from the reprogramming data area or additional-programming data area to the flash memory. The program address and 128-byte data are latched in the flash memory. The lower 8 bits of the start address in the flash memory destination area must be H'00 or H'80.

6.8.2 Erase/Erase-Verify When erasing flash memory, the erase/erase-verify flowchart shown in figure 6.11 should be followed. 1. Prewriting (setting erase block data to all 0s) is not necessary. 2. Erasing is performed in block units. Make only a single-bit specification in the erase block register (EBR).

Program/Erase Protection There are three kinds of flash memory program/erase protection; hardware protection, software protection, and error protection. 6.9.1 Hardware Protection Hardware protection refers to a state in which programming/erasing of flash memory is forcibly disabled or aborted because of a transition to reset, subactive mode, subsleep mode, watch mode, or standby mode.
Use a PROM programmer that supports the MCU device type with the on-chip Renesas Technology (former Hitachi Ltd.) 64-Kbyte flash memory (F-ZTAT64V3). A 10-MHz input clock is required. For the conditions for transition to programmer mode, see table 6.7.

6.10.3 Memory Read Mode 1. After completion of auto-program/auto-erase/status read operations, a transition is made to the command wait state. When reading memory contents, a transition to memory read mode must first be made with a command write, after which the memory contents are read. Once memory read mode has been entered, consecutive reads can be performed.

6.10.4 Auto-Program Mode 1. When reprogramming previously programmed addresses, perform auto-erasing before auto- programming. 2. Perform auto-programming once only on the same address block. It is not possible to program an address block that has already been programmed. 3. In auto-program mode, 128 bytes are programmed simultaneously. This should be carried out by executing 128 consecutive byte transfers.

9.4.4 Operation Timer F is a 16-bit counter that increments on each input clock pulse. The timer F value is constantly compared with the value set in output compare register F, and the counter can be cleared, an interrupt requested, or port output toggled, when the two values match. Timer F can also function as two independent 8-bit timers.
Page 296
TCF Increment Timing TCF is incremented by clock input (internal clock or external event input). a. Internal clock operation Bits CKSH2 to CKSH0 or CKSL2 to CKSL0 in TCRF select one of four internal clock sources (φ/32, φ/16, φ/4, or φw/4) created by dividing the system clock (φ or φw). b.
Page 297
TCF Clear Timing TCF can be cleared by a compare match with OCRF. Timer Overflow Flag (OVF) Set Timing OVF is set to 1 when TCF overflows from H'FFFF to H'0000. Compare Match Flag Set Timing The compare match flag (CMFH or CMFL) is set to 1 when the TCF and OCRF values match. The compare match signal is generated in the last state during which the values match (when TCF is updated from the matching value to a new value).
9.4.5 Application Notes The following types of contention and operation can occur when timer F is used. 16-bit Timer Mode In toggle output, TMOFH pin output is toggled when all 16 bits match and a compare match signal is generated. If a TCRF write by a MOV instruction and generation of the compare match signal occur simultaneously, TOLH data is output to the TMOFH pin as a result of the TCRF write.
Page 299
If an OCRFL write and compare match signal generation occur simultaneously, the compare match signal is invalid. However, if the written data and the counter value match, a compare match signal will be generated at that point. As the compare match signal is output in synchronization with the TCFL clock, a compare match will not result in compare match signal generation if the clock is stopped.
Page 300

Timer G 9.5.1 Overview Timer G is an 8-bit timer with dedicated input capture functions for the rising/falling edges of pulses input from the input capture input pin (input capture input signal).

Notes on Port Mode Register Modification The following points should be noted when a port mode register is modified to switch the input capture function or the input capture input noise canceler function.
Page 317
• Switching input capture input noise canceler function When performing noise canceler function switching by modifying NCS in port mode register 2 (PMR2), which controls the input capture input noise canceler, TMIG should first be cleared to 0. Note that if NCS is modified without first clearing TMIG, an edge will be regarded as having been input at the pin even though no valid edge has actually been input.
Page 318
When the pin function is switched and an edge is generated in the input capture input signal, if this edge matches the edge selected by the input capture interrupt select (IIEGS) bit, the interrupt request flag will be set to 1. The interrupt request flag should therefore be cleared to 0 before use. Figure 9.15 shows the procedure for port mode register manipulation and interrupt request flag clearing.
9.5.6 Timer G Application Example Using timer G, it is possible to measure the high and low widths of the input capture input signal as absolute values. For this purpose, CCLR1 and CCLR0 in TMG should both be set to 1. Figure 9.16 shows an example of the operation in this case.

9.7.3 Operation 16-bit Event Counter Operation When bit CH2 is cleared to 0 in ECCSR, ECH and ECL operate as a 16-bit event counter. Any of four input clock sources—φ/2, φ/4, φ/8, or AEVL pin input—can be selected by means of bits ACKL1 and ACKL0 in ECCR.
Page 344
8-bit Event Counter Operation When bit CH2 is set to 1 in ECCSR, ECH and ECL operate as independent 8-bit event counters. φ/2, φ/4, φ/8, or AEVH pin input can be selected as the input clock source for ECH by means of bits ACKH1 and ACKH0 in ECCR, and φ/2, φ/4, φ/8, or AEVL pin input can be selected as the input clock source for ECL by means of bits ACKL1 and ACKL0 in ECCR.
Page 345
IRQAEC Operation When ECPWME in AEGSR is 0, the ECH and ECL input clocks are enabled only when IRQAEC is high. When IRQAEC is low, the input clocks are not input to the counters, and so ECH and ECL do not count. ECH and ECL count operations can therefore be controlled from outside by controlling IRQAEC.

9.7.5 Application Notes 1. When reading the values in ECH and ECL, the correct value will not be returned if the event counter increments during the read operation. Therefore, if the counter is being used in the 8- bit mode, clear bits CUEH and CUEL in ECCSR to 0 before reading ECH or ECL. If the counter is being used in the 16-bit mode, clear CUEL only to 0 before reading ECH or ECL.

10.2 Register Descriptions 10.2.1 Receive Shift Register (RSR) Read/Write RSR is a register used to receive serial data. Serial data input to RSR from the RXD pin is set in the order in which it is received, starting from the LSB (bit 0), and converted to parallel data. When one byte of data is received, it is transferred to RDR automatically.
10.2.3 Transmit Shift Register (TSR) Read/Write TSR is a register used to transmit serial data. Transmit data is first transferred from TDR to TSR, and serial data transmission is carried out by sending the data to the TXD pin in order, starting from the LSB (bit 0).
10.2.5 Serial Mode Register (SMR) STOP CKS1 CKS0 Initial value Read/Write SMR is an 8-bit register used to set the serial data transfer format and to select the clock source for the baud rate generator. SMR can be read or written by the CPU at any time. SMR is initialized to H'00 upon reset, and in standby, module standby, or watch mode.

10.4 Interrupts SCI3 can generate six kinds of interrupts: transmit end, transmit data empty, receive data full, and three receive error interrupts (overrun error, framing error, and parity error). These interrupts have the same vector address. The various interrupt requests are shown in table 10.13. Table 10.13 SCI3 Interrupt Requests Vector Interrupt Abbr.
10.5 Application Notes The following points should be noted when using SCI3. 1. Relation between writes to TDR and bit TDRE Bit TDRE in the serial status register (SSR) is a status flag that indicates that data for serial transmission has not been prepared in TDR. When data is written to TDR, bit TDRE is cleared to 0 automatically.
Page 403
3. Break detection and processing When a framing error is detected, a break can be detected by reading the value of the RXD directly. In a break, the input from the RXD pin becomes all 0s, with the result that bit FER is set and bit PER may also be set.

Page 405
7. Relation between RDR reads and bit RDRF In a receive operation, SCI3 continually checks the RDRF flag. If bit RDRF is cleared to 0 when reception of one frame ends, normal data reception is completed. If bit RDRF is set to 1, this indicates that an overrun error has occurred.

9. Switching SCK function If pin SCK is used as a clock output pin by SCI3 in synchronous mode and is then switched to a general input/output pin (a pin with a different function), the pin outputs a low level signal for half a system clock (φ) cycle immediately after it is switched.

13.3.4 Boosting the LCD Drive Power Supply When a large panel is driven, the on-chip power supply capacity may be insufficient. If the power supply capacity is insufficient when V is used as the power supply, the power supply impedance must be reduced.
Section 14 Power-On Reset and Low-Voltage Detection Circuits (H8/38124 Group Only) 14.1 Overview This LSI can include a power-on reset circuit and low-voltage detection circuit. The low-voltage detection circuit consists of two circuits: LVDI (interrupt by low voltage detect) and LVDR (reset by low voltage detect) circuits. This circuit is used to prevent abnormal operation (runaway execution) from occurring due to the power supply voltage fall and to recreate the state before the power supply voltage fall when the power supply voltage rises again.
14.1.3 Pin Description The pins of the power-on reset circuit and low-voltage detection circuit are listed in table 14.1. Table 14.1 Pin Description Symbol Function Low-voltage detection circuit Vref Input Reference voltage input for low- reference voltage input pin voltage detection circuit Low-voltage detection circuit power extD Input...

Bit 7—LVD Enable (LVDE) This bit is used to control whether or not the low-voltage detection circuit is used. Bit 7 LVDE Description...
Page 457
Bit 3—LVDR Detection Level Select (LVDSEL) This bit is used to select the LVDR detection level. Select 2.3 V (typical) reset if voltage rise and drop detection interrupts are to be used. For reset detection only, Select 3.3 V (typical) reset. Bit 3 LVDSEL Description...

14.2.3 Low-Voltage Detection Counter (LVDCNT) CNT7 CNT6 CNT5 CNT4 CNT3 CNT2 CNT1 CNT0 Initial value Read/Write LVDCNT is a read-only 8-bit up-counter. Counting begins when 1 is written to LVDE. The counter increments using φ/4 as the clock source until it overflows by switching from H'FF to H'00, at which time the OVF bit in the LVDSR register is set to 1, indicating that the on-chip reference voltage generator has stabilized.
14.3 Operation 14.3.1 Power-On Reset Circuit Figure 14.2 shows the timing of the operation of the power-on reset circuit. As the power-supply voltage rises, the capacitor which is externally connected to the RES pin is gradually charged via the on-chip pull-up resistor (typ. 100 kΩ). Since the state of the RES pin is transmitted within the chip, the prescaler S and the entire chip are in their reset states.
14.3.2 Low-Voltage Detection Circuit LVDR (Reset by Low Voltage Detect) Circuit: Figure 14.3 shows the timing of the LVDR function. The LVDR enters the module-standby state after a power-on reset is canceled. To operate the LVDR, set the LVDE bit in LVDCR to 1, wait for 150 µs (t ) until the reference voltage and the low-voltage-detection power supply have LVDON...

LVDI (Interrupt by Low Voltage Detect) Circuit: Figure 14.4 shows the timing of LVDI functions. The LVDI enters the module-standby state after a power-on reset is canceled. To operate the LVDI, set the LVDE bit in LVDCR to 1, wait for 150 µs (t ) until the reference voltage and the low-voltage-detection power supply have stabilized, LVDON...
Page 464
The reference voltage, power supply voltage drop detection level, and power supply voltage rise detection level can be input to the LSI from external sources via the Vref, extD, and extU pins. Figure 14.5 shows the operational timing using input from the Vref, extD, and extU pins. First, make sure that the voltages input to pins extD and extU are set to higher levels than the interrupt detection voltage Vexd.

Operation and Cancellation Setting Procedure Using LVDR and LVDI: Settings should be made as indicated below in order to ensure proper operation of the low voltage detection circuit or to cancel operation. Figure 14.7 shows the setting timing for low voltage detection circuit operation and cancellation.
Section 15 Power Supply Circuit (H8/38124 Group Only) This LSI incorporates an internal power supply step-down circuit. Use of this circuit enables the internal power supply to be fixed at a constant level of approximately 3.0 V, independently of the voltage of the power supply connected to the external V pin.
15.2 When Not Using Internal Power Supply Step-Down Circuit When the internal power supply step-down circuit is not used, connect the external power supply to the CV pin and V pin, as shown in figure 15.2. The external power supply is then input directly to the internal power supply.

Operation Code Map Table A.2 is an operation code map. It shows the operation codes contained in the first byte of the instruction code (bits 15 to 8 of the first instruction word). Instruction when first bit of byte 2 (bit 7 of first instruction word) is 0. Instruction when first bit of byte 2 (bit 7 of first instruction word) is 1.
Number of Execution States The tables here can be used to calculate the number of states required for instruction execution. Table A.4 indicates the number of states required for each cycle (instruction fetch, read/write, etc.), and table A.3 indicates the number of cycles of each type occurring in each instruction. The total number of states required for execution of an instruction can be calculated from these two tables as follows: Execution states = I •...
