5.2.1 Configuration—PMIC supplies VCORE
• PMIC suppplies VCORE
• PMIC_EN ramps up from the host 3.3V or the host GPIO pin
• AVDD18 supplies PDn (follow AVDD18; PDn is connected to 1.8V supply)
• PMIC supplies the external VPA and AVDD18 power supply pins
• The host (1.8V/3.3V) supplies the external VIO/VIO_REF power supply pins
