This LSI includes a MultiMediaCard interface (MMCIF). The MMCIF has MMC mode. The
MMCIF is a clock-synchronous serial interface that transmits/receives data that is distinguished in
terms of command and response. A number of command/responses are predefined in the
MultiMediaCard. As the MMCIF specifies a command code and command type/response type
upon the issuance of a command, commands extended by the secure MultiMediaCard (Secure-
MMC) and additional commands can be supported in future within the range of combinations of
currently defined command types/response types.
