DMA: ePWM Interrupt Trigger Source Selection via PERINTSEL is Incorrect
0, A, B
The MODE.CHx[PERINTSEL] field bit values of 18–29 should select ePWM1SOCA–ePWM6SOCB as DMA trigger sources. Instead, PERINTSEL values of 18–29 select ePWM2SOCA–ePWM7SOCB as DMA trigger sources as shown below in Table 3-1. ePWM1SOCA and ePWM1SOCB are not implemented as PERINTSEL trigger sources.
