MSPM0G3507: ADC ENC flag automatically reset in event triggered mode after each conversion

Hello,

I want to trigger an ADC conversion with every pulse of the PWM signal created by the TIMA0.

Therefore I set the timer as event publisher and the ADC as event subscriber for the triggering which seems to work well.

Following information I can find for the ADC in AUTO sampling mode for event triggering:

•In single channel single conversion, ENC is
cleared when conversion is over
• For repeat and sequence modes, ADC waits
for HW trigger or automatically starts the next
conversion based on TRIG setting

For me it sounds that only in single channel mode the ENC would be cleared when the conversion is over.

I use sequence mode and would have expected that I do not need to set ENC bit again after each HW trigger.

But the behavior I see is that the first AD-conversion is triggered by the HW trigger, but then no more because the ENC bit is reset.

Is the observed behavior correct?

If yes, I do not really understand what sense it makes to manually set the ENC bit every time in SW when I want to use HW triggering. Could someone please explain?

Thank you in advance!

Regards,

Holger
