1.1.1 ADC Cannot Operate in Certain Low-Power Conditions

The ADC will not function when all of the following conditions exist: When the MCU system clock is sourced from LFINTOSC or SOSC and when both the BOR and FVR features are disabled.

Work around

  • Method 1: Use a system clock other than LFINTOSC or SOSC.
  • Method 2: Enable the BOR feature.
  • Method 3: Enable the FVR feature.
