Input/Output (I/O) Ports
10.1 Introduction
Twenty three (23) bidirectional input-output (I/O) pins form three 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
Although the I/O ports do not require termination for proper operation,
termination reduces excess current consumption and the possibility of
electrostatic damage.
20-pin devices have non-bonded pins. These pins should be configured
either as outputs driving low or high, or as inputs with internal pullups
enabled. Configuring these non-bonded pins in this manner will prrevent
any excess current compsumption caused by floating inputs.
