Dip Switches

There are three DIP switches S1, S2, and S3 on the back side of the PCB. S1 and S2 switches allow the user to disconnect the level shifter from the PMIC GPIOs or serial interfaces. The level shifter has pull-ups on the MCU side that can cause unwanted high state on the GPIO signals if configured in high impedance state. S3 switch is used for configuring chip select for target device in multi PMIC/stacked use case. See the Table 3-7 for the descriptions of the switches.
