I am using the chip s32k344 and want to use the external rising edge to trigger ADC sampling by configuring trgmux and adc.

Hi,

eMIOS input cannot be selected as TRGMUX source, just eMIOS output.
Try to configure PTC11 for TRGMUX_IN10 functionality and config TRGMUX to select this TRGMUX_IN10 as input source for ADC external trigger.

BR, Petr
