3) D[15::0] signifies data provided by the card to the host system.
Table 19 contains the read input timing specifications.
Note: SanDisk CompactFlash Memory cards do not assert a -WAIT signal.

Notes: 1) All timings are measured at the CompactFlash Memory Card.
2) Skews and delays from the host system driver/ receiver to the
CompactFlash Memory Card must be accounted for by the system
design.
