SLVUCU6A November 2023 – October 2024
There are two DIP switches S1 and S2 on the bottom side of the PCB. These switches allow the user to disconnect the level shifter from the PMIC GPIOs or serial interfaces. The level shifter has pull-up resistors on the MCU side that can cause unwanted high state on the GPIO signals if configured in high impedance state. See Table 2-8 for the descriptions of the switches.
