Internal oscillation
Internal oscillation
After the reset is released, the main clock starts oscillation and oscillation stabilization time (OSTS register initial value:
WDT2 immediately begins to operate after a reset has been released using the internal oscillation clock as a source

If an anomaly occurs in the main clock before oscillation stabilization time is secured, WDT2 overflows before
executing the CPU program. At this time, the CPU starts program execution by using the internal oscillation clock
as the source clock.
The CPU operation clock states can be checked with the CPU operation clock status register (CCLS).
