7            SDIO slave DAT pin is unfortunately the same pin as MTDI, which
8            controls the flash power voltage. For 3.3v flash devkits / modules /
9            kits, it conflicts with the DAT2 pullups required by the
10            specification.

12            This disables the peripheral input from the DAT2 so that we can work
13            in 1-bit mode when DAT2 is floating (pulled down). 4-bit mode is
14            therefore unavailable.
