Hello,
I am facing issues with reading the analog channel s32k344, specifically on port PTE13 ADC1_S19. I found something on the forum about VRC_CTRL. I tried disabling this function, but then the readings became 0.
What might I be forgetting to configure for the ADC readings to work?
Pay attnention to following thread:

If VRC_CTRL is disabled, then you can use it as ADC channel. Check whether you don't have it driven by GPIO or other function to GND (SIU configuration for PTE13 i.e.GPIO[141]) or whether this signal is not externally pulled down.
