[Description]
The destination operand (dst) specified by the 1st operand is added to the source operand (src) specified
by the 2nd operand and the result is stored in the destination operand (dst).
If the addition result shows that dst is 0, the Z flag is set (1). In all other cases, the Z flag is cleared (0).
If the addition generates a carry out of bit 15, the CY flag is set (1). In all other cases, the CY flag is cleared
(0).
As a result of addition, the AC flag becomes undefined.

ADDW AX, #ABCDH;
ABCDH is added to the AX register and the result is stored in the AX register.
