Writing to the real time clock
The time and date may be set by writing to the RTC registers. The new RTC time can be
updated by writing to the RTC registers. The new time only takes affect after a complete
write cycle. If the write cycle is incomplete, the new time value is discarded. A single byte
may be written to the RTC without affecting the other bytes.
