Parallel Input/Output
6.1
This section explains software controls related to parallel input/output (I/O). The MC9S08GBxxA has
seven I/O ports which include a total of 56 general-purpose I/O pins (one of these pins is output only). The
MC9S08GTxxA has six I/O ports which include a total of up to 39 general-purpose I/O pins (one pin,
PTG0, is output only). See
hardware aspects of these pins.
Many of these pins are shared with on-chip peripherals such as timer systems, external interrupts, or
keyboard interrupts. When these other modules are not controlling the port pins, they revert to
general-purpose I/O control. For each I/O pin, a port data bit provides access to input (read) and output
(write) data, a data direction bit controls the direction of the pin, and a pullup enable bit enables an internal
pullup device (provided the pin is configured as an input), and a slew rate control bit controls the rise and
fall times of the pins.
Freescale Semiconductor
Introduction
Not all general-purpose I/O pins are available on all packages. To avoid
extra current drain from floating input pins, the user’s reset initialization
routine in the application program should either enable on-chip pullup
devices or change the direction of unconnected pins to outputs so the pins
do not float.
