4 Typical System Architecture
The MPC180 works well in most load/store, memory-mapped systems. An external processor may execute
application code from its ROM and RAM, using RAM and optional non-volatile memory (such as
EEPROM) for data storage. Figure 4-1 shows an example of the MPC180 in an MPC8xx system, and
Figure 4-2 shows the MPC180 connected to the local bus of the MPC826x. In these examples, the MPC180
