3. Disabling the clock
Writing “0” to PAGER<ENATMR> disables clock operation including a carry. In the
meantime, the 1 second carry hold circuit executes time adjustment instead.
While the clock is disabled, the carry hold circuit holds a 1 second carry signal from a divider.
When the clock becomes enabled, the carry signal is output to the clock, the time is revised and
operation continues. The disabled duration for one second and more causes slowing of clocks.
