Burst
Burst lengths define the number of words the device outputs during burst READ and
WRITE operations. The device supports a burst length of 4, 8, 16, or 32 words. The device
can also be set in continuous burst mode where data is accessed sequentially up to the
end of the row.
The burst-wrap option determines if a 4-, 8-, 16-, or 32-word READ or WRITE burst
wraps within the burst length or steps through sequential addresses. If the wrap option
is not enabled, the device accesses data from sequential addresses up to the end of the
row.
