On the MC68HC908AZ60A and 64-pin MC68HC908AS60A, fifty
bidirectional input/output (I/O) form seven parallel ports. On the52-pin
MC68HC908AS60A, forty bidirectional input/output (I/O) form six
parallel ports. All I/O pins are programmable as inputs or outputs.
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.
