MPC8280 PowerQUICC II Family Reference Manual, Rev. 1

Freescale Semiconductor

IV-3

•

Chapter 40, “I2C Controller,” describes the MPC8280 implementation of the inter-integrated

circuit (I2C®) controller, which allows data to be exchanged with other I2C devices, such as

microcontrollers, EEPROMs, real-time clock devices, and A/D converters.

•

Chapter 41, “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.

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.
