C: Control Word
Bits 00 to 05 of C specify whether or not the time data will be masked for the
comparison. Bits 00 to 05 mask the seconds, minutes, hours, day, month, and
year, respectively. If all 6 values are masked, the instruction will not be exe-
cuted, the execution condition will be OFF, and the Error Flag will be turned
ON.
