Figure 4. Simplified schematic of I/Os
I/O port
When an I/O is configured as an input, FETs Q1 and Q2 are off,
creating a high impedance input with a weak pull-up to VDD. The
input voltage may be raised above VDD to a maximum of 5.5 V.
If the I/O is configured as an output, then either Q1 or Q2 is on,
depending on the state of the Output Port register. Care should be
exercised if an external voltage is applied to an I/O configured as an
output because of the low impedance path that exists between the
pin and either VDD or VSS.
