Notes:
16.SFEN = V
for IRR reads.
17.UB or LB = V
. If LB = V
IL
, then DQ<7:0> are valid. If UB = V
IL
then DQ<15:8> are valid.
18.LB must be active (LB = V
) for these bits to be valid.
19.SFEN active when either CE
= V
or CE
R
= V
IL
. It is inactive when CE
L
= CE
R
= V
IH
.
20.SFEN = V
for ODR reads and writes.
21.Output enable must be low (OE = V
) during reads for valid data to be output.
22.During ODR writes data will also be written to the memory.
