Are M9S12XDP512MAL I/O pins 5Volt Tolerant?

Hi everybody!

I'm working with a M9S12XDP512MAL and source voltage is set in 3.3V. I'd like to interface it with an LCD display that works with 5V. As the communication has to be bidirectional, the microprocessor will be able to send data to the display but I dont know what'll happen when sending data back from the display to the MCU. In datasheets I haven't seen that IO pins are 5V tolerant but it's not clear about what happens when connecting a 5V output.


Thanks in advance !
