Burst Length (BCR[2:0]) Default = Continuous 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 row.
Burst Wrap (BCR[3]) Default = No Wrap
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.
