Input/Output Ports (PORTS)
12.1 Introduction
The MC68HC08QY1A, MC68HC08QY2A and MC68HC08QY4A have thirteen bidirectional input-output
(I/O) pins and one input only pin. The MC68HC08QT1A, MC68HC08QT2A and MC68HC08QT4A has five
bidirectional I/O pins and one input only pin. All I/O pins are programmable as inputs or outputs.
12.2 Unused Pin Termination
Input pins and I/O port pins that are not used in the application must be terminated. This prevents excess
current caused by floating inputs, and enhances immunity during noise or transient events. Termination
methods include:
Never connect unused pins directly to V
Since some general-purpose I/O pins are not available on all packages, these pins must be terminated
as well. Either method 1 or 2 above are appropriate.
12.3 Port A
Port A is an 6-bit special function port that shares its pins with the keyboard interrupt (KBI) module
(see
14 Timer Interface Module
Module), the external interrupt (IRQ) pin (see
enabled using a configuration register (see
oscillator pins (see
Each port A pin also has a software configurable pullup device if the corresponding port pin is configured
as an input port.

1. Configuring unused pins as outputs and driving high or low;
2. Configuring unused pins as inputs and enabling internal pull-ups;
3. Configuring unused pins as inputs and using external pull-up or pull-down resistors.
Chapter 9 Keyboard Interrupt Module
PTA2 is input only.
When the IRQ function is enabled in the configuration register 2
(CONFIG2), bit 2 of the port A data register (PTA) will always read a logic 0.
In this case, the BIH and BIL instructions can be used to read the logic level
on the PTA2 pin. When the IRQ function is disabled, these instructions will
behave as if the PTA2 pin is a logic 1. However, reading bit 2 of PTA will
read the actual logic level on the pin.
