CP.W – Compare Word
Architecture revision:
Architecture revision1 and higher.
Description
Performs a compare between the two operands specified. The operation is implemented by
doing a subtraction without writeback of the difference. The operation sets the status flags
according to the result of the subtraction, but does not affect the operand registers.
