Branched to a new discussion

For MPC5746C, I would like to know how to use the external channels of ADC with an example code.

I understand 4 External MUX (ADCn_X[0],ADCn_X[1], ADCn_X[2], ADCn_X[3]) can be used with this and 3 select lines MA[0], MA[1], MA[2] are used to toggle the outputs.

 

But I would like to have some example code explaining how the external channels to be configured and how to read the Converted Data from the ADC_CDRn register after changing the select lines.
