Two-Supply Configuration: VDDA2P5 and VDD1P0 connected, and the VDDA1P8 pins are left unconnected. 2. Three-Supply Configuration: VDDA2P5, VDD1P0 and VDDA1P8 are all connected. VDDIO is a separate fourth supply present in both configurations. The datasheet specifies that it can either be 1.8V or 2.5V or 3.3V. Some embedded board design expose a GPIO-controlled regulator to control any one or more of these supplies. Therefore, document all four of the available supply properties.
