Data transfer

MOV

B/W/L

(EAs)

→ Rd, Rs → (EAd)

Moves data between two general registers or between a

general register and memory, or moves immediate data

to a general register.

MOVFPE

Cannot be used in the H8S/2169 or H8S/2149.

MOVTPE

Cannot be used in the H8S/2169 or H8S/2149.

POP

W/L

@SP+

→ Rn

Pops a general register from the stack.

POP.W Rn is identical to MOV.W @SP+, Rn.

POP.L ERn is identical to MOV.L @SP+, ERn.

PUSH

W/L

→ @–SP

Pushes a general register onto the stack.

PUSH.W Rn is identical to MOV.W Rn, @–SP.

PUSH.L ERn is identical to MOV.L ERn, @–SP.

LDM*3

@SP+

→ Rn (register list)

Pops two or more general registers from the stack.

STM*3

Rn (register list)

→ @–SP

Pushes two or more general registers onto the stack.

Arithmetic

operations

ADD

SUB

B/W/L

Rd ± Rs

→ Rd, Rd ± #IMM → Rd

Performs addition or subtraction on data in two general

registers, or on immediate data and data in a general

byte data in a general register. Use the SUBX or ADD

instruction.)

ADDX

SUBX

Rd ± Rs ± C

→ Rd, Rd ± #IMM ± C → Rd

Performs addition or subtraction with carry on byte data

in two general registers, or on immediate data and data

in a general register.

INC

DEC

B/W/L

Rd ± 1

→ Rd, Rd ± 2 → Rd

Increments or decrements a general register by 1 or 2.

(Byte operands can be incremented or decremented by

1 only.)

ADDS

SUBS

Rd ± 1

→ Rd, Rd ± 2 → Rd, Rd ± 4 → Rd

Adds or subtracts the value 1, 2, or 4 to or from data in a

32-bit register.
