Rd ± Rs
Performs addition or subtraction on data in two general registers, or
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.
Rd ± Rs ± C
Performs addition or subtraction with carry or borrow on byte data in
two general registers, or addition or subtraction on immediate data
and data in a general register.
Rd ± 1
Increments or decrements a general register by 1.
Rd ± 1
Adds or subtracts 1 or 2 to or from a general register
Rd decimal adjust
Decimal-adjusts (adjusts to 4-bit BCD) an addition or subtraction
result in a general register by referring to the CCR
Rd
Performs 8-bit
registers, providing a 16-bit result
Rd ÷ Rs
Performs 16-bit ÷ 8-bit unsigned division on data in two general
registers, providing an 8-bit quotient and 8-bit remainder
Rd – Rs, Rd – #IMM
Compares data in a general register with data in another general
register or with immediate data, and indicates the result in the CCR.
Word data can be compared only between two general registers.
0 – Rd
Obtains the two’s complement (arithmetic complement) of data in a
general register
