15. Clock Timer
The clock timer is a 15-bit freerun timer that counts up synchronized with the sub-clock.
Seven different interval time settings are available.
This timer provides the clock for the sub-clock’s oscillation stabilization delay timer and the watchdog timer.
This timer always counts the sub-clock, regardless of the settings in the clock selection register (CKSC) .
Clock timer functions
Clock timer interval times
SCLK : Sub-clock frequency
The values enclosed in ( ) are the times for a sub-clock frequency of 8.192 kHz.
Note that the sub-oscillation clock is divided by four to generate the sub-clock frequency. The sub-oscillation clock
operates at 32.768 kHz.
Clock periods generated by clock timer
SCLK : Sub-clock frequency
