eight registers, with 8 bytes each, for proper execution
of the burst-read function. All seven timekeeping regis-
ters are latched upon the receipt of the burst-read com-
mand. The worst-case error that can occur between the
actual time and the read time is 1s.
Writing to the Timekeeping Registers
The time and date can be set by writing to the time-
keeping registers (seconds, minutes, hours, date,
month, day, year, and century). To avoid changing the
