Preface

The H8/3150 series is a single-chip microcomputer built around a high-speed H8/300 CPU core.

On-chip facilities include an EEPROM, a ROM, a RAM, two I/O ports, a random number

generator (RNG), and a watchdog timer (WDT).

On-chip EEPROM makes the H8/3150 series ideal for applications requiring nonvolatile data

storage, including smart cards and portable data banks. Security functions protect data in the

internal memory against illegal external reading and writing.

This manual describes the H8/3150 series hardware. For details of the instruction set, refer to the

H8/300 Series Programming Manual.

2.2 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).

Registers R4L, R5, and R6 have special functions when the EEPMOV (EEPROM write)

instruction is executed.

R7 also functions as the stack pointer, used implicitly by hardware in exception handling and

subroutine calls. In assembly-language coding, R7 can also be denoted by the symbol SP. As

indicated in figure 2.2, SP (R7) points to the top of the stack.

2.2.2 Control Registers

The CPU control registers include a 16-bit program counter (PC) and an 8-bit condition code

(1) Program Counter (PC): This 16-bit register indicates the address of the next instruction the

CPU will execute. All instructions are fetched 16 bits (1 word) at a time, so the least significant bit

of PC is ignored (always regarded as 0).

(2) Condition Code Register (CCR): This 8-bit register contains internal CPU status

information, including the interrupt mask bit (I) and half-carry (H), negative (N), zero (Z),

overflow (V), and carry (C) flags.

Bit 7—Interrupt Mask Bit (I): Masks interrupts when set to 1. This bit is set to 1 at the

beginning of exception handling.

Bit 6—User Bit (U): Can be written and read by software for its own purposes (using the LDC,

STC, ANDC, ORC, and XORC instructions).

Bit 5—Half-Carry Flag (H): When the ADD.B, ADDX.B, SUB.B, SUBX.B, CMP.B, or NEG.B

instruction is executed, this flag is set to 1 if there is a carry or borrow at bit 3, and is cleared to 0

otherwise.

The H flag is used implicitly by the DAA and DAS instructions.

When the ADD.W, SUB.W, or CMP.W instruction is executed, the H flag is set to 1 if there is a

carry or borrow at bit 11, and is cleared to 0 otherwise.

Bit 4—User Bit (U): Can be written and read by software for its own purposes (using the LDC,

STC, ANDC, ORC, and XORC instructions).

Bit 3—Negative Flag (N): Indicates the most significant bit (sign bit) of data.

Bit 2—Zero Flag (Z): Set to 1 to indicate zero data, and cleared to 0 to indicate non-zero data.

Bit 1—Overflow Flag (V): Set to 1 when an arithmetic overflow occurs, and cleared to 0 at other

times.

Bit 0—Carry Flag (C): Set to 1 when a carry occurs, and cleared to 0 otherwise. Used by:

• Add instructions, to indicate a carry

• Subtract instructions, to indicate a borrow

• Shift and rotate instructions, to store the value shifted out of the end bit

The carry flag is also used as a bit accumulator by bit manipulation instructions.

Some instructions leave some or all of the flag bits unchanged. The LDC, STC, ANDC, ORC, and

XORC instructions enable the CPU to load and store CCR, and to set or clear selected bits by

logic operations. The N, Z, V, and C flags are used as branching conditions for conditional

branching (Bcc) instructions.

Refer to the H8/300 Series Programming Manual for the action of each instruction on the flag

bits.

2.2.3 Initial Register Values

When the CPU is reset, the program counter (PC) is loaded from the vector table and the I bit in

CCR is set to 1. The other CCR bits and the general registers are not initialized. In particular, the

stack pointer (R7) is not initialized. To prevent program crashes, the stack pointer should be

initialized by software, by the first instruction executed after a reset.

2.3 Data Formats

The H8/300 CPU can process 1-bit data, 4-bit (BCD) data, 8-bit (byte) data, and 16-bit (word)

data.

• Bit manipulation instructions operate on 1-bit data specified as bit n (n = 0, 1, 2, ..., 7) in a byte

operand.

• All arithmetic instructions except ADDS and SUBS can operate on byte data.

• The MOV.W, ADD.W, SUB.W, CMP.W, ADDS, SUBS, MULXU (8 bits × 8 bits), and

DIVXU (16 bits ÷ 8 bits) instructions operate on word data.

• The DAA and DAS instructions perform decimal arithmetic adjustments on byte data in

packed BCD form. Each nibble of the byte is treated as a decimal digit.
