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 whether 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.
