Function
Rd ± Rs
Performs addition or subtraction on data in two general registers, or
Rd ± Rs ± C
Performs addition or subtraction with carry or borrow on byte data in
Rd ± #1
Increments or decrements a general register.
Rd ± #imm
Adds or subtracts immediate data to or from data in a general register.
Rd decimal adjust
Decimal-adjusts (adjusts to packed BCD) an addition or subtraction
Rd Rs
Performs 8-bit 8-bit unsigned multiplication on data in two general
Rd ÷ Rs
Performs 16-bit ÷ 8-bit unsigned division on data in two general
Rd – Rs, Rd – #imm
Compares data in a general register with data in another general register
0 – Rd
Obtains the two’s complement (arithmetic complement) of data in a
addition on immediate data and data in a general register. Immediate
data cannot be subtracted from data in a general register. Word data can
be added or subtracted only when both words are in general registers.
