6.10 ADC71

ADC Module

Category

Functional

Function

ADC12 stops converting when ENC and SC bits are set simultaneously and ADC12 was previously set to trigger from a source that was not the SC bit.

Description


When using the ADC12 after being setup and triggered by a trigger source that is not the ADC12SC bit (ADC Start Conversion), if ADC12ENC (ADC Enable) and ADC12SC bits are set simultaneously, then ADC12BUSY flag stays high and ADC12SC does not get cleared. As a result, the ADC conversion never finishes.

Workaround


Set ADC12ENC and ADC12SC bits with separate instructions if the trigger source is changed from a source that is not ADC12SC.
