CCS/LAUNCHXL-F28027: ADCINTSOCSEL1 does not initiate auto-trigger

Hello,

The ADC result is updated on every TBCTR=0 (As I have set it to that), irrespective of ADCINTSOCSEL1 selection.

Here is my configuration(I am using SOC1):

EOC1 triggers ADCINT1 :
- AdcRegs.ADCCTL1.bit.INTPULSEPOS = 1;
  
  AdcRegs.INTSEL1N2.bit.INT1SEL = 1; //EOC1 triggers ADCINT1
INT1CONT is disabled (Also, I have ensured that my interrupt routine is smaller than my PWM period)
ADCINTSOCSEL1.SOC1 = 1 (ADCINT1 triggers SOC1)

But even then, ADCRESULT1 is updated at TBCTR=0 only.

Dhrumeel,

Can you read back your register settings in software or through CCS to make sure that your values were written to the register as expected?

Dhrumeel,
Wanted to see if there were any updates regarding Tommy's questions?

I am sorry sir, but the controller was given to me for a project. The organisation has now changed the controller to 28335. So, I did not get the opportunity to check register values.
