40.5 GPIO power supply configuration
The GPIO pins on this device are organized in five separate banks. Each bank has associated VDD/VSS
power supply pairs. The five banks of GPIO can be powered independently, allowing these banks to be run
at different voltages in the 3.0 V to 5.5 V range.
Table 40-4 describes the GPIO banks, their main functions, supply pins and associated port pins. For full
details of GPIO functionality, refer to Chapter 3, Signal Description.
