9.3.5 Sleep Mode Operation

If there is no ongoing write operation, the NVMCTRL will enter a sleep mode when the system enters a sleep mode.

If a write operation is ongoing when the system enters a sleep mode, the NVM block, the NVM Controller, and the system clock will remain ON until the write is finished. This is valid for all sleep modes, including Power-Down sleep mode.

The EEPROM Ready interrupt will wake up the device only from Idle sleep mode.

The page buffer is cleared when waking up from sleep.
