Description
Given that the result of a subtraction operation performed by a SUB.B, SUBX.B, or NEG.B
instruction on 4-bit BCD data is contained in an 8-bit register Rd and the carry and half-carry
flags, the DAS instruction adjusts the contents of the 8-bit register Rd (destination operand) by
adding H'00, H'FA, H'A0, or H'9A according to the table below.
Available Registers
Rd: R0L to R7L, R0H to R7H
