[Description]
The A register, CY flag and AC flag are decimally adjusted from their contents. This instruction carries out
an operation having meaning only when the BCD (binary coded decimal) data is subtracted and the
subtraction result is stored in the A register (in all other cases, the instruction carries out an operation having
no meaning).
See the table below for the adjustment method.
If the adjustment result shows that the A register contents are 0, the Z flag is set (1). In all other cases,
the Z flag is cleared (0).
