MPC8260 PowerQUICC II Family Reference Manual, Rev. 2
Freescale Semiconductor IV-3
• Chapter 40, “Parallel I/O Ports,” describes the four general-purpose I/O ports A–D. Each signal in
the I/O ports can be configured as a general-purpose I/O signal or as a signal dedicated to
supporting communications devices, such as SMCs, SCCs. MCCs, and FCCs.

detailed applications notes.
Architecture Documentation
Documentation is available in the following document:
• Programming environments manuals—These books provide information about resources defined
by the PowerPC architecture that are common to processors that implement the PowerPC
architecture. There are two versions, one that describes the functionality of the combined 32- and
64-bit architecture models and one that describes only the 32-bit model.
