16.5.8 Operation in Standby Mode Status
Note 1. The SNOOZE mode can only be specified when the high-speed on-chip oscillator clock is selected as fCLK.
Note 2. In the STOP mode, detecting a DTC activation source enables transition to SNOOZE mode and DTC transfer.
After completion of transfer, the system returns to the STOP mode. However, since the code flash memory and the data
flash memory are stopped during the SNOOZE mode, the flash memory cannot be set as the transfer source.
Note 3. When an A/D conversion end interrupt is set as a DTC activation source from the A/D converter SNOOZE mode function,
release the SNOOZE mode using the A/D conversion end interrupt to start CPU processing after completion of DTC
transfer, or use a chain transfer to set the A/D converter SNOOZE mode function again (writing 0 to the AWC bit and then
writing 1 to the AWC bit).
