2.
When a port pin serves as an output, its pull-up resistor is automatically disabled, even though the
port's pull-up resistor is enabled by bit settings in the pull-up resistor mode register (PUMOD).
Port6 is a schmitt trigger input.
If this port is set to output ports, the input signal is not transmitted to the MUX.
