Memory Map
Each memory resource in the MPC885 is mapped within a contiguous block of 16 Kbytes of memory. The
location of this block within the global 4-Gbyte physical memory space can be mapped on 64-Kbyte
resolution through an implementation-specific special-purpose register (SPR) called the internal memory
map register (IMMR). See
the internal memory map, and
Table 2-1. MPC885 Internal Memory Map (IMMR[14–15]=00)
