The EN/PB/VSENSE pin is used to enable or disable the PMIC. This pin can be configured in one of three ways: EN, PB or VSENSE. The table below shows the default configuration for this pin. Please note, if the FSD (First supply detection) feature is enabled, the device goes from "No Power" to "Active" state, executing the power-up sequence as soon as the voltage on VSYS is above the POR threshold. In this scenario, the EN/PB/VSENSE pin is ignored ONLY during the first power-up.
