Pin classification

Note. The input and input/output pins are all 5V tolerant. The maximum input voltage that can be applied to these pins are 5.5V, if supply voltage is within

the recommended operating voltage. If the input voltage is between 5.5V and VDD which is smaller than the recommended operating voltage, the

device doesn’t breakdown itself, but it maybe generate reverse current from the input pins to the supply voltage (VDD). Although input/output pins in

input mode can accept 5.5V as the maximum input voltage, the maximum output voltage in output mode is VDD level. It is forbidden to add more

voltage than VDD to output mode bidirectional pins (external pull-up or other means).
