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 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.
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.
