Memory Mapping Control (S12XMMCV3)
18.1
Introduction
This section describes the functionality of the module mapping control (MMC) sub-block of the S12X
platform. The block diagram of the MMC is shown in
Figure
18-1.
The MMC module controls the multi-master priority accesses, the selection of internal resources and
external space. Internal buses, including internal memories and peripherals, are controlled in this module.
The local address space for each master is translated to a global memory space.
