Multiple MPC8280s Configured from Boot EPROM
For a complex system with multiple MPC8280 devices that may each be configured differently,
configuration is done by assigning one configuration master and multiple configuration slaves. The
MPC8280 that controls the boot EPROM should be the configuration master—RSTCONF tied to GND.
The RSTCONF inputs of the other MPC8280 devices are tied to the address bus lines, thus assigning them
as configuration slaves. See Figure 5-7.
