Pinmux template for 3.3V tolerance

We checked the Jetson nano module pinmux template, and realize the configuration for “3.3V tolerance”. For example, the I2C bus could be enable or disable “3.3V tolerance” .
Does it working as the description?
How do change the status of the pins that pull-up by a resistor?

Hello @felixch

On the pinmux spreadsheet the customizable cells are marked in orange.

The types of pin configurations supported are described in the Jetson Nano Module Data Sheet document which can be found here:

Please take a look into section 3, where the pins are described. You can see which types of pins tolerate which voltage.
