reads. Burst reads are limited to within a partition, it is not possible to do a burst read across the
partition boundary. A block diagram showing signal connections is shown in
Figure 18
. This is an
ideal interface, and some glue logic may be required if the processor does not provide any or all of
these signals.
Figure 19
shows a synchronous burst mode read timing diagram. Note that only one
address is needed from the processor to generate four valid data outputs.
