the device (both VDD and VBAT go to 0V). The bit is set
regardless of whether VDD or VBAT is applied first. The loss
of only one of the supplies does not set the RTCF bit to “1”.
On power-up after a total power failure, all registers are set
to their default states and the clock will not increment until
at least one byte is written to the clock register. The first
valid write to the RTC section after a complete power failure
resets the RTCF bit to “0” (writing one byte is sufficient).
