3.1 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 3-1.
The MMC module controls the multi-master priority accesses, the selection of internal resources . 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.
