CP.B – Compare Byte
Architecture revision:
Architecture revision1 and higher.
Description
Performs a compare between the lowermost bytes in 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.
Operation:
I.
Syntax:
I.
Operands:
I.
Status Flags:
