Function
Rd
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
Performs addition or subtraction with carry on data in two general
registers, or addition or subtraction with carry on immediate data and
data in a general register.
Rd
Increments or decrements a general register
Rd
Adds or subtracts 1 or 2 to or from a general register
Rd decimal adjust
Decimal-adjusts (adjusts to packed 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
Performs 16-bit
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.
