1. Write to this register after setting the PRC1 bit in the PRCR register to 1 (write enable).
2. The PM20 bit becomes effective when 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 cleared to 0 by program.
4. Writting to the following bits has no effect when the PM21 bit is set to 1:
5. Setting the PM22 bit to 1 results in the following conditions:
6. For NMI function, the PM24 bit must be set to 1(NMI function). Once this bit is set to 1, it cannot be set to 0 by

Do not execute WAIT instruction when the PM21 bit is set to 1.
•
• The on-chip oscillator starts oscillating, and the on-chip oscillator clock becomes the watchdog timer
• The CM10 bit in the CM1 register cannnot be written. (Writing 1 has no effect, stop mode is not entered.)
• The watchdog timer does not stop in wait mode.
