37. MultiMedia Card Interface (MCI)
37.1
6254C–ATARM–22-Jan-10
Description
The MultiMedia Card Interface (MCI) supports the MultiMedia Card (MMC) Specification V3.11,
the SDIO Specification V1.1 and the SD Memory Card Specification V1.0.
The MCI includes a command register, response registers, data registers, timeout counters and
error detection logic that automatically handle the transmission of commands and, when
required, the reception of the associated responses and data with a limited processor overhead.
The MCI supports stream, block and multi-block data read and write, and is compatible with the
Peripheral DMA Controller (PDC) channels, minimizing processor intervention for large buffer
transfers.
The MCI operates at a rate of up to Master Clock divided by 2 and supports the interfacing of 2
slot(s). Each slot may be used to interface with a MultiMediaCard bus (up to 30 Cards) or with a
SD Memory Card. Only one slot can be selected at a time (slots are multiplexed). A bit field in
the SD Card Register performs this selection.
The SD Memory Card communication is based on a 9-pin interface (clock, command, four data
and three power lines) and the MultiMedia Card on a 7-pin interface (clock, command, one data,
three power lines and one reserved for future use).
The SD Memory Card interface also supports MultiMedia Card operations. The main differences
between SD and MultiMedia Cards are the initialization process and the bus topology.
