Hi,
I would like to know what register values need to be updated to change the select lines of the external multiplexers connected to MPC5746C.
I understand we need to use ADCn_MA[0..2] to change the select lines of the external multiplexers from 0 through 8, but exactly what register and which bit information is not provided in the MPC5746C reference manual.
Please help.
It does not work this way.
Just choosing of external channel number will assert particular MA lines to select external channel with using of external multiplexer.
For instance if you perform conversion of channel 66 by ADC0, then ADC module automatically asserts ADCn_MA[0..2] as 0b010 to connect particular MUX input to MCU's ADC input and conversion is performed over ADC1_X[0] line.
Hope it helps
