Counting by the WDT does not proceed if the frequency divisor is changed but the multiplier is
not.
1. In the initial state, IFC = B'0 and PFC[2:0] = B'011.
2. Set the desired value in the IFC and PFC2 to IFC0 bits. The values that can be set are limited
3. After the register bits (IFC and PFC2 to PFC0) have been set, the clock is supplied of the new
