Chapter 3 Module Mapping Control (MMCV4) Block Description
3.1.1
3.1.2
Some of the registers operate differently depending on the mode of operation (i.e., normal expanded wide,
special single chip, etc.). This is best understood from the register descriptions.
3.2
All interfacing with the MMC sub-block is done within the core, it has no external signals.
3.3
A summary of the registers associated with the MMC sub-block is shown in
descriptions of the registers and bits are given in the subsections that follow.
