Twenty one (21) bidirectional input-output (I/O) pins form five parallel
ports. All I/O pins are programmable as inputs or outputs. All individual
bits within port A, port C, and port D are software configurable with pullup
devices if configured as input port bits. The pullup devices are
automatically and dynamically disabled when a port bit is switched to
output mode.
Connect any unused I/O pins to an appropriate logic level, either V

operation, termination reduces excess current consumption and the
possibility of electrostatic damage.
