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 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
Rd
Performs signed multiplication on data in two general registers: either 8
bits
Rd ÷ Rs
Performs unsigned division on data in two general registers: either 16
bits ÷ 8 bits
16-bit quotient and 16-bit remainder.
