MPC533 Address Map

The internal memory map is organized as a single 4-Mbyte block. The user can assign this
block to one of eight locations by programming a register in the USIU (IMMR[ISB]). The
eight possible locations are the first eight 4-Mbyte memory blocks starting with address
0x0000 0000 (refer to Figure 1-3). The programmability of the internal memory map
location allows the user to implement a multiple-chip system.
