Notes:1) –WAIT is not supported in this mode.

2)The maximum load on -WAIT is 1 LSTTL with 50 pF (40pF below 120nsec Cycle Time) total load. All times are in nanoseconds. Dout signifies data provided by the CompactFlash Storage Card to the system. The -WAIT signal may be ignored if the -OE cycle to cycle time is greater than the Wait Width time. The Max Wait Width time can be determined from the Card Information Structure. The Wait Width time meets the PCMCIA PC Card specification of 12µs but is intentionally less in this specification.
