Figure 12-166 describes the IOMUX_ENABLE multilplexer, which is controlled by the
MMC_SSCFG_PHY_CTRL_1_REG[31] IOMUX_ENABLE bit.
A. i represents a valid
instance of 4-bit MMCSD only. See the device data sheet for specifics.
B. x=3 for MMCSD (4-bit wide
data bus)
C. Only MMCi_CLK, MMCi_CMD and
MMCi_DAT[n:0] are routed through the IOMUX_ENABLE multiplexer. MMCi_SDCD and
MMCi_SDWP are not routed through the IOMUX_ENABLE multiplexer.
D. The IOMUX_ENABLE multiplexer
does not affect the signal functions selected from the respective PADCONFIG
register for the MMCi_SDCD or MMCi_SDWP pins.
