Context
Based on the datasheet, both VBAT and VDDIO have a working range comprehensive of the value 3.3V (VBAT IS 3V-4.2V and VDDIO is 1.8V-3.3V).
Question
We would like to use a single power supply for both VBAT and VDDIO, initial testing is ok and everything is working. Do any of you know a reason/best practice for keeping them separated?
Thanks in advance
