Software configuration for unused pins

[PreethiCapG]

Hi Team,

I have 16 unused GPIO pins and 3 SPI pins (Pin 36 to 38) and left them unconnected in the design. I couldn't find any data regarding handling unused pins in the datasheet/ manuals.

Can anyone please let me how the unconnected pins should be configured in software. Whether it should configured as input, output or any other specific configuration.

Thanks,
Preethi
