Precautions during programming
The special data registers DT9054 to DT9056/ DT90054 to DT90056, in which the values of the internal
calendar timer are stored, cannot be specified directly for D. To change the value of the internal calendar
timer, store the addition results in a separate memory area, and then use the F0 (MV) instruction to transfer
the value to DT9054 to DT9056/DT90054 to DT90056.
