ePWM: ePWM One-Shot/CBC Trip Event DCxEVTy.force Does Not Set the Trip Condition

Revisions Affected

0, A, B

Details

The DCxEVTy.force signal can be used as input for one-shot trip events and cycle-by-cycle trip events. Setting DCxCTL[EVT1/2FRCSYNCSEL] = 1 (passes the DCxEVT signal through the async path) does not properly set the one-shot or cycle-by-cycle trip event condition, and the trip event is missed.

Workaround

For devices with DCxCTL.EVT1/2FRCSYNCSEL and DCxCTL.EVT1/2LATSEL, there are two options. Otherwise, Sync Path is the only option available for use in one-shot or cycle-by-cycle trip events.

Async Path (passes the DCxEVT signal through the async path)

The following configurations must be made to latch the one-shot or cycle-by-cycle trip condition through the async path:

  1. DCxCTL.EVT1/2FRCSYNCSEL = 1
  2. DCxCTL.EVT1/2LATSEL = 1

Sync Path (passes the DCxEVT signal through the sync path)

  1. DCxCTL.EVT1/2FRCSYNCSEL = 0
