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 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.
Rd ÷ Rs → Rd
Performs unsigned division on data in two general registers: either 16
bits ÷ 8 bits → 8-bit quotient and 8-bit remainder or 32 bits ÷ 16 bits
→ 16-bit quotient and 16-bit remainder.
