1. Rewrite the PLC1 register after the PRC0 bit in the PRCR register is set to "1" (write enable).
2. Rewrite the PLC1 register after the CM17 bit in the CM1 register is set to "0" (main clock) .
3. When the CM21 bit in the CM2 register is set to "0" (clock selected by the CM17 bit), if the PLC11 bit
4. Do not rewrite the PLC12 bit if the PLL clock is the CPU clock source.

is set to "1" before the CM17 bit is set to "1" (PLL clock as CPU clock source), the PLL clock divided-
by-2 or divided-by-3 becomes the clock source of the CPU clock and peripheral function clock.
