Notes:
1. Parameters t
CYC
,t
CH
and t
CL
are different in Flow-through and Pipeline mode of operation and can be different for different ports (Refer AC Timing characteristics).
2. Chip Selected (CE0 = L and CE1 =H). True for both ports.
3. Address indicated is the Internal Address used and is dependent on the Address counter control inputs for that cycle.
4. “Am” refers to matched address. “Aa” and “Ab” refer to any other valid address.
5. During address collision the data validity is guaranteed only if t
CCO
is greater than the minimum specified (Refer AC timing characteristics).
