Sercom0 was configured for AI (SPI). Clock signal has not been generated.
Now the response from the ADC module. need to test with the inputs.

AI testing was done by giving AI and AV inputs to ADC and verified
the below is log file link

This log looks acceptable for AI all channels.
Observation
a. 2 to 4 count variations noticed, may be due to noise from the setup (compare with PLCIO Prog. model. doc(v1p10.worksheet sheet ADC Noise ))
b. count went to 0 value for one sample (ch1, 2, 4)- @DEVI PRIYAA check this alone
@Sumanth D : Please add one sheet in the excel, create a table with " measured inputs, observed ADC value, calculated output" for each channel
