1.2 System Architecture
The MPC180E works in load/store, memory-mapped systems. Figure 1-2 and Figure 1-2
show example system architectures. An external processor may execute application code
from its ROM and RAM, using RAM and optional nonvolatile memory (such as EEPROM)
for storing data. The MPC180E resides in the processor memory map; therefore, an
application requiring cryptographic functions simply writes to and reads from the
appropriate memory location.
The MPC180E interfaces to the MPC8xx system bus or to the local buss of the MPC8260.
