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. (Subtraction on
immediate data and data in a general register cannot be performed in
bytes. Use the SUBX or ADD instruction.)
Rd ± Rs ± C → Rd, Rd ± #IMM ± C → Rd
Performs addition or subtraction with carry on data in two general
registers, or on immediate data and data in a general register.
Rd ± 1 → Rd, Rd ± 2 → Rd
Adds or subtracts the value 1 or 2 to or from data in a general register.
(Only the value 1 can be added to or subtracted from byte operands.)
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-bit × 8-bit → 16-bit or 16-bit × 16-bit → 32-bit.
Rd × Rs → Rd
Performs signed multiplication on data in two general registers: either 8-
bit × 8-bit → 16-bit or 16-bit × 16-bit → 32-bit.
Rd ÷ Rs → Rd
Performs unsigned division on data in two general registers: either 16-bit
÷ 8-bit → 8-bit quotient and 8-bit remainder or 32-bit ÷ 16-bit → 16-bit
quotient and 16-bit remainder.
