MKL28Z what voltage level to register positive logic 1?

Hello,

 

I've look at the MKL28Z datasheet and reference manual but I could not find a direct statement that says exactly what input voltage to GPIO will register a solid positive logic 1 to the MCU?   I'm not sure if I should just take any googled generic voltage level for Vdd = 3.3V or can I?

 

For positive logic:

Is 0 - 0.5V  =  logic 0?      >1.65 V = logic 1?

 

Please advise.

 

Thanks for the help.

 

MI
