Hi, following example code shows simultaneous conversion of two channels. If is given by targeting of command into CBuffer0 or CBuffer1 which also specify used A/D converter. The example is written for different device using the same ADC.

Example MPC5674F eQADC+eDMA Single_Scan CW210 

As start point you may use following one I have written for MPC5644A:
