5.2 Configuration Headers

The TPS65219EVM has multiple headers that can be used to change the input supply for some of the power rails. It also includes headers that allows changing the specific functions of the PMIC using the multi-function pins. Table 5-2 list all the headers and the expected configuration for each selection.
