1. Rewrite this register after setting the PRC1 bit in the PRCR register to 1 (write enable).
2. The PM20 bit become effective when the PLC07 bit in the PLC0 register is set to 1 (PLL on). Change the PM20
3. Once this bit is set to 1, it cannot be set to 0 in a program.
4. Setting the PM22 bit to 1 results in the following conditions:

bit when the PLC07 bit is set to 0 (PLL off). Set the PM20 bit to 0 (2 waits) when PLL clock > 16MHz.
1. Rewrite this register after setting the PRC0 bit in the PRCR register to 1 (write enabled).
2. This bit can only be modified when the PLC07 bit = 0 (PLL turned off). The value once written to this bit
3. Before setting this bit to 1, set the CM07 bit in the CM0 register to 0 (main clock), set bits CM17 to CM16
4. Multiply by 6 is available Normal-ver. only.

0
The on-chip oscillator starts oscillating, and the on-chip oscillator clock becomes the watchdog timer count source.
The CM10 bit in the CM1 register is disabled against write. (Writing a 1 has no effect, nor is stop mode entered.)
The watchdog timer does not stop when in wait mode or hold state.
