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).
