Overview

NOTE

The information in this document is accurate for revision 3.x silicon and

later (in other words, for orderable part numbers ending in A or B). For

information on revision 1.1 silicon and earlier versions, see the MPC8347E

PowerQUICC II Pro Integrated Host Processor Hardware Specifications.

See Section 22.1, “Part Numbers Fully Addressed by This Document,” for

silicon revision level determination.
