ADS documentation states that "4-bit" mode SDIO interface is included in the BitsyXb developement system, but the BitsyXb manual only shows the signals on the J7 header necessary for SPI mode SDIO. Is this a mistake?
Is a 4-bit mode SDIO interface available?

The SD card interface is a 4 bit SD I/O Interface.
The current configuration on J7 is not SPI but a 1-Bit interface that functions just like MMC.
There is a rework for the jumper cable from J7 to the interface card to get the 4 bit functionality.
