Hi@lihui1
you can find this information in S32K-DS.pdf : S32K1xx Data Sheet Rev.14,08/2021
5.3 DC electrical specifications at 3.3 V Range.
5.4 DC electrical specifications at 5.0 V Range.
So it's not current-limiting resister ? It's pullup/pulldown resistor?
and a liitle more question we want to know:
If GPIO used as input, has this resister there on the input circuit?
It seems like input current will flow through this resistor as below
OK! Thank you!
