Function
Rd ± Rs
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
Performs addition or subtraction with carry on data in two general
registers, or on immediate data and data in a general register.
Rd ± 1
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
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 CCR to produce 4-bit BCD data.
Rd
Performs unsigned multiplication on data in two general registers: either
8 bits
Rd
Performs signed multiplication on data in two general registers: either 8
