I am attempting to configure the ADCSAR on my CYBLE022001-00 module to monitor battery voltage. I will need to run it in differential mode as my Vcc is slightly less than 3.30v, and I need to detect a battery voltage range from 4.20v to 2.5v.

Just looking for guidance on pin configuration and setup.

There is a sample program for battery voltage monitors.  Select file open example and search for ble and battery test.

Here is your program I added the Diff input. I am running PSOC Creator 4.0.  I changed the device to your device. You will need to have a resistance divider to measure over 3.3 Volts.
