All timings are measured at the PC Card.
Skews and delays from the host system driver/receiver to the PC Card must be accounted for by
the system design.
Minimum time for WAIT# negated to IOWR# negated is 0 ns, but minimum IOWR# timing
must still be met.
D[15::0] signifies data provided by the host system to the PC Card .
