Function
(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.
Cannot be used in the H8S/2169 or H8S/2149.
Cannot be used in the H8S/2169 or H8S/2149.
@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.
Rn → @–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.
@SP+ → Rn (register list)
Pops two or more general registers from the stack.
Rn (register list) → @–SP
Pushes two or more general registers onto the stack.
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
register. (Immediate byte data cannot be subtracted from
byte data in a general register. Use the SUBX or ADD
instruction.)
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.
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.)
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.
Rd decimal adjust → Rd
Decimal-adjusts an addition or subtraction result in a
general register by referring to the CCR to produce 4-bit
BCD data.
