These settings detail the default monitoring on VCCA. When voltage is first applied to VCCA that is greater than UVLO, the PMIC sets VCCA_VMON_EN high and sets VCCA_PG_SET to 3.3V or 5V based on sensed VCCA voltage. The settings found in registers VCCA_VMON_CTRL and VCCA_PG_WINDOW can be changed though I2C after startup.
