I found the input buffer enabled at unused GPIO pins on 2.1 of KBA232509 as below URL.
https://community.infineon.com/t5/Knowledge-Base-Articles/Traveo-II-Automotive-Body-Controller-FAQ-G...
Is this the GPIO state after reset?

I confirmed that the input buffer is disabled with the default register settings on TV2BE-4M register TRM as below.
GPIO_PRTx_CFG . IN_EN0[3:3]=0 ; input buffer disabled

Which one is correct at the GPIO status after reset?
Also, if the KBA is correct (input buffers are enabled), Which documentation can I confirm that it is correct?

thank you,

Hi @MaKi_350451 ,

The correct info is :

T2G Body Entry Arch TRM (002-19314 Rev. *H)
22.6.1 Drive Modes -> High-Impedance
High-impedance drive mode with input buffer disabled is the default pin reset state.,

 

We have have updated the same above info in KBA also internally and it will be published soon publicly.

Thank you for understanding.

BR.
