Description
Given that the result of an addition operation performed by an ADD.B or ADDX instruction on
4-bit BCD data is contained in an 8-bit register Rd and the carry and half-carry flags, the DAA
instruction adjusts the contents of the 8-bit register Rd (destination operand) by adding H'00, H'06,
H'60, or H'66 according to the table below.
