MCDB0 - MCDB3
When the MCI is configured to operate with SD memory cards, the width of the data bus can be
selected in the MCI_SDCR register. Clearing the SDCBUS bit in this register means that the
width is one bit; setting it means that the width is four bits. In the case of multimedia cards, only
the data line 0 is used. The other data lines can be used as independent PIOs.
