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.)

Increments or decrements a general register by 1 or 2. (Byte operands
can be incremented or decremented by 1 only.)
