the on-chip PLL circuits are used.
3. Power must be supplied to VDD-CPG and VSS-CPG regardless of whether or not the
on-chip crystal resonator is used.
4. Power must be supplied to VDD-RTC and VSS-RTC regardless of whether or not the
on-chip RTC is used.
5. At least the RTC power supply must be supplied in hardware standby mode.
