DAS (Decimal Adjust Subtract)

DAS

<Description>

Given that the result of a subtraction operation performed by the SUB.B, SUBX, or NEG

instruction on 4-bit BCD data is contained in an 8-bit general register and the carry and half-

carry flags, the DAA instruction adjusts the result by adding H'00, H'FA, H'A0, or H'9A to the

general register according to the table below.

Valid results are not assured if this instruction is executed under conditions other than those

stated above.

I: Previous value remains unchanged.

H: Unpredictable.

N: Set to "1" if the adjusted result is

negative; otherwise cleared to "0."

Z: Set to "1" if the adjusted result is zero;

otherwise cleared to "0."

V: Unpredictable.

C: Previous value remains unchanged.
