Figure 5-121. MMC/SD/SDIO 2 Interface—High-Speed SDR JC64—Transmitter Mode⁽¹⁾⁽²⁾
(1) In sdmmc2_dat[n:0], n up to 7
(2) In this section, the MMC/SD/SDIO output data and command signals are driven on the falling clock edge.
In this case, the MMCHS_HCTL[2] HSPE bit is set to 0. The controller is by default in this mode to maximize hold timings.
For more information, see MMC/SD/SDIO / MMC/SD/SDIO Functional Description / Output Signals Generation / Generation on Falling
Edge of MMC Clock section of the OMAP4460 TRM.
