MSPM0G3507: Timer capture mode

Dipkumar Vala

Part Number: MSPM0G3507

Tool/software:

I'm using the timx_timer_mode_capture_edge_capture_LP_MSPM0G3507_nortos_ticlang example for edge captures.

After reading the capture value, I want to reset the Capture/Compare value (CC_01) back to zero. I tried using the DL_Timer_getCaptureCompareValue() function, but it didn’t work.

Is there a way to reset the Capture/Compare value (CC_01) to zero after reading it?

As far as I know the CC registers are writeable in Capture mode. I expect you can use something like:

> DL_Timer_setCaptureCompareValue(CAPTURE_0_INST, 0, DL_TIMER_CC_0_INDEX);

Keep in mind that this introduces a race, where you lose the capture value for an edge which arrives in the meantime. Also, the value of doing this is not obvious.

I used the same function but it it not working.

How do you tell that it doesn't work? What is your test case?
