RA4M1 Input voltage level

Hi all

In the input voltage level(P414) of the RA4M1 Users manual, min is VCC x 0.8, but Max is not listed.

What is the Max value when the operating voltage is 3.3V?

Is it possible to receive 3.4~4.4V from the P414 as a high enable signal?

Or should I change to 5V tolerant ports?

Regards.
