5.3.3
SLEEP State
Sleep State is entered when the VBAT level signal is removed from the KEYSW pin and the PWREN SPI bit is a logic low. In
Sleep state all outputs and current sources and sinks are off and the device consumes less than IVPWR(SS) µA. Applying a VBAT
level to the KEYSW pin will force the device to exit the Sleep state and generate a POR.
