to 8-digit BCD seconds-only data and outputs the result to D and D+1.
Flags
Precautions The maximum value for the source data is 9,999 hours, 59 minutes, and 59
seconds (35,999,999 seconds).
Examples When CIO 0.00 turns ON in the following example, the hours/minutes/sec-
onds data in D200 and D201 (34 hours, 17 minutes, and 36 seconds) is con-
