52 / 224 page  Table 17. SAI features SAI features SAI1 I2S, LSB or MSB-justified, PCM/DSP, TDM, AC'97 X Mute mode X Stereo/mono audio frame capability. X 16 slots X Data size configurable: 8-, 10-, 16-, 20-, 24-, 32-bit X FIFO size X (8 words) SPDIF X PDM X(2) 1. X = supported. 2. Only signals D[3:1], and CK[2:1] are available. 3.41 Secure digital input/output and MultiMediaCards interface (SDMMC) The SDMMC (SD/SDIO embedded MultiMediaCard eMMC™ host interface) provides an interface between the AHB bus and SD memory cards, SDIO cards and eMMC devices. The MultiMediaCard system specifications are available through the MultiMediaCard association website at www.jedec.org, published by the MMCA technical committee. SD memory card and SD I/O card system specifications are available through the SD card Association website at www.sdcard.org. The SDMMC features include the following: • Compliance with Embedded MultiMediaCard System Specification Version 5.1 Card support for three different databus modes: 1-bit (default), 4-bit and 8-bit (HS200 SDMMC_CK speed limited to maximum allowed I/O speed) (HS400 is not supported). • Full compatibility with previous versions of MultiMediaCards (backward compatibility). • Full compliance with SD memory card specifications version 6.0 (SDR104 SDMMC_CK speed limited to maximum allowed I/O speed, SPI mode and UHS-II mode not supported). • Full compliance with SDIO card specification version 4.0 Card support for two different databus modes: 1-bit (default) and 4-bit (SDR104 SDMMC_CK speed limited to maximum allowed I/O speed, SPI mode and UHS-II mode not supported). • Data transfer up to 208 Mbyte/s for the 8-bit mode (Depending maximum allowed I/O speed). • Data and command output enable signals to control external bidirectional drivers • IDMA linked list support The MultiMediaCard/SD bus connects cards to the host. The current version of the SDMMC supports only one SD/SDIO/eMMC card at any one time and a stack of eMMC. Table 18. SDMMC features SDMMC modes/features SDMMC1 Variable delay (SDR104, HS200) X SDMMC_CKIN X SDMMC_CDIR, SDMMC_D0DIR X SDMMC_D123DIR X 1. X = supported.
