External Bus Interface and Memory Map
This chapter describes the MPC180 address map, the External Bus Interface (EBI), and EBI
registers.
3.1 Execution Unit Registers
Each MPC180 execution unit has a dedicated set of registers. The MPC180 has a unified
memory map that allows software addressibility to all internal registers. Figure 3-1 lists
each MPC180 register and its 12-bit MPC180 chip address.
