SN65DP141: Unused Pins

Part Number: SN65DP141

Hi team,

I have two questions about SN65DP141 design:

1. We are going to use two channels of IN/OUT pins in SN65DP141. What should we do to the unused IN/OUT pins?

2. In I2C mode we can disable the unused IN/OUT pins, can we do the same thing in GPIO mode? Is it ok if we don't disable the unused channels?

Thank you,

Muwei Zheng
