        SDIO slave DAT pin is unfortunately the same pin as MTDI, which
        controls the flash power voltage. For 3.3v flash devkits / modules /
        kits, it conflicts with the DAT2 pullups required by the
        specification.
        
        This disables the peripheral input from the DAT2 so that we can work
        in 1-bit mode when DAT2 is floating (pulled down). 4-bit mode is
        therefore unavailable.
