(1) When MMCSD0 or MMCSD1 is used, any non-MMC signal function multiplexed with the respective pins are not available. This is due
to the MMC having an internal IO multiplexer which is controlled by MMCSD0/1_SS_PHY_CTRL_1_REG[31] IOMUX_ENABLE. This
internal IO multiplexer is primary for the signal functions associated with MMCSD pins, and the PADCONFIG’s MUXMODE is
secondary. Additionally, the internal IO multiplexer affects all of the MMCSD0 or MMCSD1 pins, regardless of configured data bus
width. Therefore, when MMCSD0/1_SS_PHY_CTRL_1_REG[31] IOMUX_ENABLE = 0, the respective MMCSD pins are configured for
eMMC/SD functionality, regardless of the PADCONFIG [MUXMODE] setting.
(2) Each of these signals should have an external 50kΩpull-up resistor connected to the corresponding power supply.
