IOIS16 Delay Falling from Address
IOIS16 Delay Rising from Address
Wait Delay Falling from IOWR
IOWR high from Wait high
Wait Width Time (Default Speed)
(Set Feature Speed <68 mA.)
Notes: The maximum load on -WAIT, -INPACK, and -IOIS16 is 1 LSTTL with 50pF total load. All times are in
nanoseconds.
Minimum time from -WAIT high to -IOWR high is 0 nsec, but minimum -IOWR width must still be met.
Din signifies data provided by the system to the CompactFlash Memory Card.
