3.2 Enable Settings

This section describes the PMIC rails that are enabled in Active and Standby state. Any rail that is disabled by default has the option to be enabled through I2C once the device is in Active state and I2C communication is available. The transition between Active and Standby state can be triggered by hardware (when MODE/STBY pin is configured as STBY) or by software (register field: STBY_I2C_CTRL).
