6.3.4
Note: " Δ " ( due to buffer driving delay and wire loading) is 20 nS.
6.3.5
Note: Ports are read during S5P2, and output data becomes available at the end of S6P2. The timing data are referenced to
ALE Low to WR Low
Data Valid to WR Low
Data Hold from WR High
Port Input Setup to ALE Low
Port Input Hold from ALE Low
Port Output to ALE
WR Pulse Width
ALE, since it provides a convenient reference.
