Original question:
MSPM0G3507: ADC ENC flag automatically reset in event triggered mode after each conversion
Tool/software:
I m using Sequence mode then a set PWRDN and ENC bit of CTL0. But after convertion of all configured channel ENC is clear aven PWRDN automaticaly cleared. So Next other trig event is ignored.
Specification say:
16 PWRDN R/W 0h Power down policy 0h = ADC is powered down on completion of a conversion if there is no pending trigger 1h = ADC remains powered on as long as it is enabled through software.
see below all register berfore Set ENC bit:
Hi Pierre,
As the other thread you posr here:https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1281756/mspm0g3507-adc-enc-flag-automatically-reset-in-event-triggered-mode-after-each-conversion
Have you enable the repeat mode here? I found it seems not enabled.

Hi,
This will not synchronise ADC with event but keep ADC continously do convertion.
This ADC is for BLDC current sens, so it should be synchonized with PWM.
And if I understood correctly below "1" means that is clear ONLY by software ?
Hi Pierre,
In previous thread, you got the recommendation to set the last channel as " keep next ADC convert will triggered by event", then it will require an external trigger (software or event) to start next sequence conversion, which means it will not keep ADC continously do conversion.
And if I understood correctly below "1" means that is clear ONLY by software ?
This is for power supply, not for adc ENC.
If user set single mode, the ENC always cleared after one complete conversion.
Using repeat mode, and always set the last channel as: valid trigger (shown in below)
