7.2. How to Initialize the Real-time Clock?
This section explains how to initialize the real-time clock.
Perform initialization using the start bit (WTCR:ST).
Write "0" instead of "1" to the start bit to reset all the bits of the Hour/ Minute/ Second counters and the
subsecond counter (22-bit down counter) to "0" (initialization) and to stop counting.
