12. Watch Clock Output
The watch clock output circuit divides the oscillator clock by means of the timebase timer, and outputs the set
division clock. Can be set to 1/32, 1/64, 1/128, or 1/256 of oscillator clock.
Watch clock output circuit
The watch clock output circuit is disabled in reset and stop modes. It is enabled in normal run modes, sleep
mode, and pseudo clock mode.
If the timebase timer is cleared while the watch clock output circuit is in use, clock output cannot be conducted
normally.
