The three Time writing registers are only writable concomitantly and must be written in the order as shown below:
1. RT_SEC
2. RT_MIN
3. RT_HOUR

? SEC:
The range is 0-59 encoded in Binary Coded Decimal (BCD). The lowest four bits encode the units, the higher bits encode
the tens.
This field must not be written unless the time counter has been stopped.

? HOUR:
Depending on bit AMPM, the range can be 1-12 or 0-23, encoded in BCD. The lowest four bits encode the units, the higher
bits encode the tens. This field must not be written unless the time counter has been stopped.
? AMPM:
This bit controls/reflects the AM/PM indicator in 12-hour mode.
0: AM.
1: PM.
