Data Read Cycle
Notes :
1. Data memory access time is 8 T
2. " ∆ " (due to buffer driving delay and wire loading) is 20 nS.
Data Write Cycle
Note : " ∆ " (due to buffer driving delay and wire loading) is 20 nS.
Port Access Cycle
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 RD Low
Data Hold after RD High
Data Float after RD High
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
RD Low to Data Valid
RD Pulse Width
WR Pulse Width
ALE, since it provides a convenient reference.
