Zero Flag (Z): The Zero Flag is set if the result of an operation is zero.


Auxiliary Carry Flag (AC): The Auxiliary Carry Flag is used for binary-coded decimal (BCD) arithmetic. It is set if there is a carry out of the low nibble (4 bits) during an operation.

Carry Flag (CY): The Carry Flag is set if there is a carry out of the most significant bit (MSB) during an operation.
