[quote user="Chris Sterzik"] Eric, Thank you for pointing this out. I believe there is an omission but will need to confirm. I tried a fairly simple test and found DMA_CH5_EUSCIB2RX0 is triggered from the EUSCIB2 RXIFG while the DMA_CH1_EUSCIB2RX2 is not. Again, my suspicion is that only the RX0 and TX0 are valid for eUSCIBx but I will need to confirm. [/quote] thanks for checking this out Chris. Could you verify eUSCI_Bn TX0 and eUSCI_Bn RX0 settings work. And can you find out what the other triggers do? ie. If channel 0 is set to SRCCFG {3,4,5} what would trigger channel 0. Similarly for channel {1,2,3,4,5,6,7}, srccfg {3,4,5} you will probably go talk to the msp432 h/w folks. It is clearly a multiplexer feeding each of the trigger inputs for each of the 8 dma channels. The question is what does settings 3,4,and 5 select.
