When CIO 0.00 is ON in the following example, D100, D110,
and CY will be added as 4-digit BCD values, and the result will
be output to D120.
When CIO 0.00 is ON in the following example, D101, D100,
D111, D110, and CY will be added as 8-digit BCD values, and
the result will be output to D121 and D120.
