May I not supply voltage to VCCIO during power up and configuration?

Hi.

You are not right.

All I/Os pins are tied to an internal weak pull-up during Power Up and Reset. See page 244.

I see that VCCIO is Not Monitored by the POR Circuitry. See page 321. I repeat my question. May I not supply voltage to VCCIO during power up and configuration?
