How to find the channel number of the ADC port

[Riyasma07]

I've selected an ADC from PTB10 which is ADC0_X[2]. But when I try to find the channel number of that port I'm little bit confused.

In the reference manual ADC0_X[2] is mentioned as same for channels 80 to 87. Please help me to find the exact channel of a port pin.

Hi

Please refer to the discussion in S32K3 ADC Use of external channels

I think that information was not clear.

See I have selected an ADC (adc0_x,2). And which physical channel name should I choose?

[Robin_Shen]

Are you using the ADC0_MA[2:0] signals with an external analog multiplexer? If not, selecting X2_ChanNum80-87 is the same, which means ADC (adc0_x,2) is selected.

Are you saying we can choose any channel from 80 to 87 if ADC0_X[2] is selected??

It seems you didn't connect the external analog multiplexer. So you can choose any channel from 80 to 87 if ADC0_X[2] is selected.
