SUBW
• 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 15, the CY flag is set (1). In all other cases, the CY flag is
• As a result of subtraction, the AC flag becomes undefined.
SUBW AX, #ABCDH; ABCDH is subtracted from the AX register contents and the result is stored in the AX
specified by the 1st operand and the result is stored in the destination operand (dst) and the CY flag.
The destination operand can be cleared to 0 by equalizing the source operand (src) and the destination
operand (dst).
