... Application Note AN2667/D Rev. 0. 12/2003 Multi-Controller Hardware Development for the MPC5xx Family Application Note This application note details how to configure the Steven McQuade microcontrollers to satisfy the requirements of a multi-controller system. It also describes the hardware for such a system by using an example of TECD Applications the dual MPC561-4 evaluation board (EVB) that was developed to demonstrate multi-controller functionality ...

Freescale Semiconductor, Inc. Another possibility is that every MPC5xx in the system will take the RCW from its own internal flash (RSTCONF=1 for all devices). This way may be preferable, since there is no requirement to drive the external data ...
