MPC5643L _etimer

I think I have some misconception about the DMA request of the eTimer module.

Q1: I don’t know how to use the INTDMA register. 

Example: if I want to use the DMA read requests for CAPT1,then I should set the .ICF1DE bit (INTDMA) .

My question is whether I need to configure the conrresponding DMA channel source , channel source address and destination addrress? 

My confusion is that the ICF1DE bit which equals 1 has showed the souce address is CAPT1, does we need configure the source address again?


Did anone have conrresponding example codes ?


Thanks very much!
