Clock monitor
Main clock
If an anomaly occurs in the main clock before the oscillation stabilization time is secured, WDT2 overflows
before the CPU starts executing the program. At this time, the CPU starts executing the program by using the
internal oscillator clock as the source clock.
Caution In the emergency operation mode, do not access on-chip peripheral I/O registers other than
The CPU operation clock states can be checked by using the CPU operation clock status register (CCLS).

Operation
those for the interrupt function, port function, WDT2, and timer M, which can operate on the
internal oscillator clock. In addition, operating CSIB0 to CSIB4 and UARTA0 by using an
external clock is also prohibited.
