Timing wave form read/write cycle
[7]
Notes:
1. Both Flow-through and Pipeline Inputs/Outputs indicated.A particular port is configured in Flow-through mode if PL/FT for that port is driven low,
and in Pipeline mode if PL/FT is driven high or left unconnected.
2. Parameters t
CYC
,t
CH
and t
CL
are different in Flow-through and Pipeline modes of operation.(Refer AC Timing characteristics)
3. CE is an internal signal.CE = H implies 'Chip is Deselected' (CE0 = H or CE1 =L), CE = L implies 'Chip is Selected' (CE0 = L and CE1 =H).
Timings indicated for CE hold good for CE0 and CE1
4. BEn refers to any one of the 4 byte controls [n= 3,2,1 or 0] and DATA OUT refers to the corresponding Byte.
5. Counter set in “Load” mode (ADS = L,INC = X,RPT = H).
6. OE is an asynchronous input.
7. All timings are similar for both ports.
8. Invalid write. Memory Content of the selected location may get corrupted and should be re-written before future readback.
9. Write (A11) is invalid in Pipeline mode and Write (A8) is invalid in Flow-through mode. Memory Content of the selected location may get corrupted and should be re-written
before future readback.
