SECTION 3
MEMORY MAP
This section discusses the internal memory map (including key registers) of the MPC823e.
Each memory resource is mapped within a contiguous block of 16K storage. The location of
this block within the global 4G real storage space can be mapped on 64K resolution through
an implementation specific special register called the internal memory map register (IMMR).
Refer to Section 12.12.1.2 Internal Memory Map Register for more information.
