4.2 Configuration Headers

The TPS65219EVM-SKT has multiple headers that can be used to change the input supply for some of the power rails. The PCB also includes headers that allows changing specific functions of the PMIC using the multi-function pins. TPS65219 Configuration Headers list all the headers and the expected configuration for each selection.
