device to starting of the sector data transfer. Note that the host does
not need to read the Status register for the reading of a single sector
or the last sector in multiple-sector reading. If the timing to read
the Status register does not meet above condition, normal data
transfer operation is not guaranteed.
When the host new command even if the device requests the data
transfer (setting in DRQ bit), the correct device operation is not
guaranteed.
