device to 50 ms after the completion 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.

When the host new command even if the device requests the data transfer (setting in DRQ bit), the correct device operation is not guaranteed.
