4.17
Six High Voltage capable inputs are implemented with the following features:
When used as analog inputs to sense voltages outside the module a series resistor must be used on the used input. When a Lx
input is not selected in the analog multiplexer, the voltage divider is disconnected from that input. When a Lx input is selected in
the analog multiplexer, it will be disconnected in low power mode if configured as Wake-up input. Unused Lx pins are
recommended to be connected to GND to improve EMC behavior.
