+Technology</title><shortdesc>MultiMediaCard (MMC) is a low cost data storage and communication
+media, and is defined by the <i>MultiMediaCard System Specification</i></shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p> The MMC specification is published by the <xref href="http://www.mmca.org" scope="external">MultiMediaCard Association</xref>. </p>
+<p>Communication is based on a 7-pin serial bus designed to operate in a low
+voltage range (2.0 - 3.6V). The MultiMediaCard specification defines a communication
+protocol referred to as MMC mode (0-20MHz). In addition, for compatibility
+with existing controllers, MultiMediaCards may offer an alternative communication
+protocol which is based on the SPI standard (0-5MHz). </p>

+following features of the MultiMediaCard System Specification are not provided

+<li id="GUID-75439A4B-28C8-58A6-81A8-92BF08F490A1"><p>Stream read and write

+supported. </p> </li>
+<li id="GUID-26F8D809-57EF-5CCB-99A5-BFDCA59A5F76"><p>The MultiMediaCard System
+Specification includes a feature where a MultiMediaCard can be put into a
+disconnected state. This can be performed on a card which is currently in
+the programming state, i.e. writing data to the disk. To place that card into
+the disconnected state involves placing another card into the transfer state,
+which means giving the other card the current data transfer focus. A disconnected
+card will not terminate the programming operation and, if re-selected, moves
+back to the programming state. The Symbian platform MultiMediaCard controller
+does not support this mode of operation even if the underlying hardware interface
+does. </p> </li>
