7.2.2.1
Write DRQ interval time
For write sectors and write multiple operations 3.8 us is inserted from the end of negation of the DRQ bit
until setting of the next DRQ bit.
7.2.2.2
Read DRQ interval time
For read sectors and read multiple operations the interval from the end of negation of the DRQ bit until
setting of the next DRQ bit is as follows:
°
In the event that a host reads the status register only before the sector or block transfer DRQ interval
DRQ interval
............
