This LSI supports a multimedia card interface (MMCIF). The MMC mode interface can be
utilized. The MMCIF is a clock-synchronous serial interface that transmits/receives data that is
distinguished in terms of command and response. A number of commands/responses are
predefined in the multimedia card. As the MMCIF specifies a command code and command
type/response type upon the issuance of a command, commands extended by the secure
multimedia card (Secure-MMC) and additional commands can be supported in the future within
the range of combinations of currently defined command types/response types.
24.1
The MMCIF has the following features:
• Supports a subset of the MultiMediaCard System Specification Version 3.1
• Supports MMC mode
• Incorporates 64 data-transfer FIFOs of 16 bits
• Supports DMA transfer
• Four interrupt sources
• Interface via the MMCCLK output (transfer clock output) pin, the MMCCMD input/output
FIFO empty/full (FSTAT), command/response/data transfer complete (TRAN), transfer error
(ERR), and FIFO ready (FRDY)
(command output/response input) pin, and the MMCDAT input/output (data input/output) pin
