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. 3FFFF (IFFFF for AS9C25128M2036L
)
is the Mailbox for port B and 3FFFE (IFFFE for AS9C25128M2036L) is the Mailbox for port A.
5. “Aa” and “Ab” refer to any other valid address other than 3FFFF or 3FFFE (IFFFF or IFFFE for AS9C25128M2036L).
