CMPE : CoMPare for Equality

This alias of CMPU means that this opcode is used only because it modifies the Z bit and the carry flag is not used.

When the two operands are equal, Z is set to 1 (otherwise it is reset to 0) and you can use the EQ (EQual) or NEQ (Not EQual) conditions to enable the following instruction(s).
