To allow multiple CMPSS at a time to affect DCA/BEVTx events and trip actions, there is a OR logic to bring together ALL trip inputs (up to 15) from sources external to the ePWM module and feed into DCAH, DCAL, DCBH, and DCBL as a “combinational input” using the DCTRIPSEL register. This is configured by selecting “Trip combination input” (value of 0xF) in the DCTRIPSEL register.
There is a discrete choice of which trip inputs to put through the combinational logic for generating the DCAH, DCAL, DCBH, and DCBL signals. This is achieved using the DCAHTRIPSEL, DCALTRIPSEL, DCBHTRIPSEL, and DCBLTRIPSEL register selections. Inputs selected for combinational input are passed through to the DCTRIPSEL register.
