J5 can be removed and resistors populated on the board for a permanent ADCIN4 configuration. R33 is the
resistor connected to ground in the ADCIN4 resistor divider and R25 is the resistor connected to LDO_3V3 in
the ADCIN4 resistor divider. Populating these resistors with values that correspond to the same ADCIN decoded
value as configured with the ADCIN4 switch set provides the same configuration for ADCIN4.
An analogous process can be followed for all four jumpers to permanently configure any ADCIN configuration.
Table 2-1 details which resistor pads correspond to which ADCIN switch set and jumper.

2.4 Push Buttons
Push button SW5 controls the FAULT_IN GPIO input. Pressing the SW5 button sets FAULT_IN to logical high.
The use of FAULT_IN is detailed in the TPS25730 data sheet (SLVSGP9).
