Function
Rd ± Rs
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
Performs addition or subtraction with carry or borrow on
byte data in two general registers, or on immediate data
and data in a general register.
Rd ± 1
Increments or decrements a general register by 1 or 2.
(Byte operands can be incremented or decremented by
1 only.)
Rd ± 1
Adds or subtracts the value 1, 2, or 4 to or from data in a
32-bit register.
Rd decimal adjust
Decimal-adjusts an addition or subtraction result in a
general register by referring to the CCR to produce 4-bit
BCD data.
Rd
Performs unsigned multiplication on data in two general
registers: either 8 bits
16 bits
Rd
Performs signed multiplication on data in two general
registers: either 8 bits
16 bits
Rd ÷ Rs
Performs unsigned division on data in two general
registers: either 16 bits ÷ 8 bits
remainder or 32 bits ÷ 16 bits
bit remainder.
