3.2.3 Advisory

ePWM: ESM Source for Trip Zone is not Supported

Revisions Affected

0, A, B

Details

An ESM_GEN_EVENT coming from the ESM may not properly trip the ePWM, and should not be used.

The following path should not be used to trip PWM:

ESM Subsystem (SYS ESM) → ESM_GEN_EVENT → PWM XBAR → ePWM Digital Compare → ePWM Trip Zone

Workaround

Use the error source to generate an NMI interrupt from the respective ESM CPU instance. Within the NMI interrupt, issue a software write using the Driverlib function below to force a trip on the PWM output.
