How to use PTC5 of S32K314 as ADC sampling

[shunyizhang]

Hi,nxp

I am using the ADC function of S32K314, and PTC5 pin is one of all my ADC acquisition channels. Besides, all other ADC channels are collected normally, and the abnormal problems are marked in the figure below. Would you like to know what is special about PTC5 when it is used as ADC analog quantity acquisition?

Hi@shunyizhang

If you just use PTC5 as the ADC pin, I think this has no special impact

1.PTC5 can be used as the TDI pin of JTAG, please confirm whether the port is used as the TDI pin.

2.Is it possible to observe the impact of the debugger on the pin when it is connected and disconnected through an oscilloscope?
