Reset state is mode dependent. In single-chip or bootstrap modes, port C pins are high-impedance in-
puts. It is customary to have an external pull-up resistor on lines that are driven by open-drain devices.
In expanded or test modes, port C pins are data bus inputs and outputs and PORTC is not in the mem-
ory map.
