SUB
• The source operand (src) specified by the 2nd operand is subtracted from the destination operand (dst)
• If the subtraction shows that dst is 0, the Z flag is set (1). In all other cases, the Z flag is cleared (0).
• If the subtraction generates a borrow out of bit 7, the CY flag is set (1). In all other cases, the CY flag is
• If the subtraction generates a borrow for bit 3 out of bit 4, the AC flag is set (1). In all other cases, the AC

The destination operand can be cleared to 0 by equalizing the source operand (src) and the destination
operand (dst).
