Notes:
1. Set the PM17 bit in the PM1 register to 1 (one wait).
2. When the frequency is over this value, set the FMR17 bit in the FMR1 register to 0 (one wait) or the PM17 bit in
the PM1 register to 1 (one wait)
3. Set the PM17 bit in the PM1 register to 1 (one wait). When using the 125 kHz on-chip oscillator clock or sub
clock as the CPU clock source, a wait is not necessary.
