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 IORD# negated is 0 ns, but minimum IORD# width
must still be met.
D[15::0] signifies data provided by the PC Card to the host system.
