About This Manual

This manual describes the multimedia card (MMC)/secure digital (SD) card controller in the TMS320DM644x Digital Media System-on-Chip (DMSoC). The MMC/SD card is used in a number of applications to provide removable data storage. The MMC/SD controller provides an interface to external MMC and SD cards. The MMC/SD protocol performs the communication between the MMC/SD controller and MMC/SD card(s).

Notational Conventions

This document uses the following conventions.

∙Hexadecimal numbers are shown with the suffix h. For example, the following number is 40 hexadecimal (decimal 64): 40h.

∙Registers in this document are shown in figures and described in tables.

–Each register figure shows a rectangle divided into fields that represent the fields of the register. Each field is labeled with its bit name, its beginning and ending bit numbers above, and its read/write properties below. A legend explains the notation used for the properties.

–Reserved bits in a register figure designate a bit that is used for future device expansion.
