Figure 4-7 True IDE Mode I/O Read 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 -IORD high is 0 nsec, but minimum -IORD width must still be met.
Dout signifies data provided by the CompactFlash Memory Card to the system.
