Although this document is written from the perspective of
the MPC8548E, most of the material applies to the other
family members, such as MPC8547E, MPC8545E, and
MPC8543E. When specific differences occur, such as pinout
differences and processor frequency ranges, they are
identified as such.
For specific PVR and SVR numbers, see the MPC8548E
