BURST READ
Extended BURST WRITE
Q
ADV suspnds burst.
(NOTE4)
(NOTE5)
BYTE WRITE signals are
ignored for first cycle when
ADSP initialtes burst.
Note:
1. Q(A2) refers to output from address A2. Q (A2 + 1) refers to output from the next internal burst
address following A2.
2.
CE2
and CE2 have timing identical to
CE
. On this diagram, when
CE
is LOW ,
CE2
is
LOW and CE2 is HIGH. When
CE
is HIGH ,
CE2
is HIGH and CE2 is LOW.
3.
OE
must be HIGH before the input data setup and hold HIGH throughout the data hold time.
This prevents input/output data contention for the time period to the byte write enable inputs being
sampled.
4.
ADV
must be HIGH to permit a WRITE to the loaded address.
5. Full width WRITE can be initiated by GW LOW or GW HIGH and BWE ,BW1-BW4
LOW.
