Figure 4-8 True IDE Mode I/O Write Timing Diagram
Notes: The maximum load on -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.
