ADC failed

[LinWeiyang]

I tested the ADC pins using the S32K312 chip and found that the IO pin PTE18 did not successfully convert data, but the other two pins, PTC7 and PTD28, both worked successfully as ADCs. In the IDE, the configurations for these pins are almost identical. Observing the schematic diagram, I did not find any pull-down situation for the PTE18 pin

Hi

Please tell me what version of RTD you are using.
Please check bit 6 MUX_MODE_EN_ADC1_S23 of 38.2.51 Read Write GPR On Functional Reset 4 (DCMRWF4).

Best Regards,
Robin

Please try to call Siul2_Port_Ip_Init and check it again.

I used SW32K3_RTD_R21-11_4.0.0_P04_D2312 as my RTD.However,I changed it to SW32K3_S32M27x_RTD_R21-11_5.0.0_D2410,the result is same.
