It is observed that some of the channels of ADC channel group does not capture the conversion results of the supplied voltage on those channels. However, the same channels do capture the right results for the same supplied voltage; if they are individually configured in a ADC channel group (single ADC channel in the group).
Test environment :
Board : LP eval board
Input : 2.5V input on each tested channel
Config : For ach ADC HW unit 3+ channels are mapped into a ADC channel group which needs to be triggered using SW trigger.
Affected channels :
- ADC0_2
- ADC1_2
- ADC2_1
- ADC2_2
- ADC3_1
- ADC3_2
- ADC4_1
These tests were performed on the LP board for the available ADC channels.
Untested channels : ADC0_4, ADC1_4, ADC2_4, ADC3_4, ADC4_2, ADC4_3, ADC4_4
