Advisory

ePWM: Trip Events Will Not be Filtered by the Blanking Window for the First 3 Cycles After the Start of a Blanking Window

Revisions Affected

B, C

Details

The Blanking Window will not blank trip events for the first 3 cycles after the start of a Blanking Window. DCEVTFILT may continue to reflect changes in the DCxEVTy signals. If DCEVTFILT is enabled, this may impact subsequent subsystems that are configured (for example, the Trip Zone submodule, TZ interrupts, ADC SOC, or the PWM output).

Workarounds

Start the Blanking Window 3 cycles before blanking is required. If a Blanking Window is needed at a period boundary, start the Blanking Window 3 cycles before the beginning of the next period. This works because Blanking Windows persist across period boundaries.
