Hi team,
In our design, pin no 93 -ADC1_MA[0] (ADC1 -> mux_output0 -> PTC27) used to read voltage.
I configured this pin, this pin default direction is output not configurable as a input.
How can i configure and read ADC value from this ADC1_MA[0]?

Hi,
ADCx_MA signals are output decode signals, cannot be used as ADC input.
The ADC provides three external decode signals which it uses to select one channel out of eight in the external analog multiplexers. There can be a maximum of four such multiplexers used to connect the 32 external channels. The ADC automatically sets the decode signals to control these external analog multiplexers, based on the current external channel selected for conversion.
