Chapter 6
Parallel Input/Output
6.1
This chapter explains software controls related to parallel input/output (I/O). The MC9S08AW60 has
seven I/O ports which include a total of 54 general-purpose I/O pins. See
Connections” for more information about the logic and hardware aspects of these pins.
Many of these pins are shared with on-chip peripherals such as timer systems, communication systems, or
keyboard interrupts. When these other modules are not controlling the port pins, they revert to
general-purpose I/O control.
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 to V
