frequency clock is stopped. Before transition to these modes, the watchdog timer should be disabled.
The Watchdog timer is consists of the binary counters that work using the system clock (fsys) as an input.
To detect malfunctions (runaways) of the CPU caused by noise or other disturbances, the binary counter of
Additionally, it is possible to resolve the problem of a malfunction (runaway) of the CPU by connecting the
The watchdog timer begins operation immediately after a reset is cleared.
If not using the watchdog timer, it should be disabled.
The watchdog timer cannot be used in the STOP mode, SLEEP mode and SLOW mode where high-speed
In IDLE mode, its operation depends on the WDMOD <I2WDT> setting.
Also, the binary counter is automatically stopped during debug mode.
