Best way to make use of GPI pins?

[jc2020]

I've read on the forums that MISO pins are good for this purpose.

What downsides are there to using the GPI pins as opposed to the GPIO pins for purely receiving input to the MCU?

Thanks .

You don't get any built-in pullups/pulldowns on the GPI pins; aside from that they're good for everything input-related.
