Module Mapping Control (MMCV4) Block Description
3.1
This section describes the functionality of the module mapping control (MMC) sub-block of the S12 core
platform.
The block diagram of the MMC is shown in
The MMC is the sub-module which controls memory map assignment and selection of internal resources
and external space. Internal buses between the core and memories and between the core and peripherals is
controlled in this module. The memory expansion is generated in this module.
