Using eMIOS as a hardware trigger for SDADC

I am using the MPC5746R to collect data samples from the SDADC. Currently I am using a DMA transfer to remove conversion results from the data queue. If I wanted to employ a hardware trigger with the eMIOS, how would I go about doing so?


I have reviewed the 'Input Muxing' sheet in the 'IO_Signal_Description_and_Input_Multiplexing_Tables.xlsx', and found that the corresponding MSCR register is 970, for the Start Trigger mechanism. But I cannot find any mapping between this input and the eMIOS pins. I would like to also implement the DMA enable gate.
