NOTES:

NOTES:
1. Set the PLC1 register after the PRC0 bit in the PRCR register is set to 1 (write enable).
2. If the PM21 bit in the PM2 register is set to 1 (disables a clock change), a write to the the PLC1 register has no effect.
3. Set the PLC1 register while the PLC07 bit is 0 (PLL stopped).The PLC1 register can be written only once.
4. Set registers PLC0 and PLC1 simultaneously in 16-bit units.

1. Set the PLC0 register after the PRC0 bit in the PRCR register is set to 1 (write enable).
2. If the PM21 bit in the PM2 register is set to 1 (disables a clock change), a write to the PLC0 register has no effect.
3. Set bits PLC02 to PLC00 while the PLC07 bit is 0. Bits PLC02 to PLC00 can be written only once.
4. Enter wait mode or stop mode after the CM17 bit is set to 0 (main clock as CPU clock source) and then the PLC07 bit to 0.
5. Set registers PLC0 and PLC1 simultaneously in 16-bit units .
