DDF[7:0] — Data Direction for Port F
0 = Bits set to zero to configure corresponding I/O pin for input only
1 = Bits set to one to configure corresponding I/O pin for output
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.
