Read Buffer — E4h
The Read Buffer command allows the host to read the contents of the sector
buffer. When issued, the device sets the BSY bit and sets up the sector buffer
data in preparation for the read operation. When the data is ready, the DRQ bit
is set and the BSY bit in the Status register are set and cleared, respectively.
