DAS (Decimal Adjust Subtract)
<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.
