This document provides bring-up guidelines for designs
based on the MPC8555E and the MPC8541E devices from
the PowerQUICC III family of integrated communications
processors (collectively referred to throughout this
document as PowerQUICC III). This document can also be
useful in debugging newly designed systems by highlighting
the aspects of a design that merit special attention during
initial system startup.

Getting Started
This section outlines recommendations to simplify the first
phase of design. Before designing a system with a
PowerQUICC III device, it is recommended that you
familiarize yourself with the available documentation,
software, microcodes, models, and tools.
