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 on for this TRM which is linked to a specific part number. 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.
