Here are some possible valid DRQ blocks that could be used
by the device for this command (these are the BC values a device
could use):
1) A series of bursts: 20 bytes, 40 bytes, 20 bytes,
40 bytes, 5 bytes.
>>>>>> last DRQ block would be '6'
2) A series of bursts: 40 bytes, 30 bytes, 10 bytes,
40 bytes, 5 bytes.
>>>>>> last DRQ block would be '6'
3) A series of bursts: 10 bytes, 40 bytes, 30 bytes,
20 bytes, 10 bytes, 15 bytes.
