SD/SDIO/MMC Mode
In block write mode, the card holds the DATA0 line low while it is busy. SSP must wait
for the DATA0 line to be high for one clock cycle before starting to write to a block.
In block read mode, the card begins sending the data when it is ready. The first bit transmitted
by the card is a Start bit 0. Prior to the 0 Start Bit, the DATA0 bus is high. After the Start
bit is received, data is shifted in. The SSP bus width is set using the BUS_WIDTH bit in
the HW_SSP_CTRL0 register.
In 1-bit bus mode, the block data is formatted as shown in
In 4-bit I/O mode, the block data is formatted as shown in
In 8-bit bus mode, the block data is formatted as shown in
