Function
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 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 or borrow on 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 CCR to produce 4-bit BCD data.
Rd × Rs → Rd
Performs unsigned multiplication on data in two general registers:
either 8 bits × 8 bits → 16 bits or 16 bits × 16 bits → 32 bits.
Rd × Rs → Rd
Performs signed multiplication on data in two general registers:
either 8 bits × 8 bits → 16 bits or 16 bits × 16 bits → 32 bits.
