Burst lengths define the number of words the device outputs during a burst READ oper-
ation. The device supports a burst length of 4, 8, or 16 words. The device can also be set
in continuous burst mode where data is output sequentially without regard to address
boundaries; the internal address wraps to 000000h if the device is read past the last
address. WRITE bursts are always performed using continuous burst mode.
The burst wrap option determines if a 4-, 8-, or 16-word burst READ wraps within the
burst length, or steps through sequential addresses. If the wrap option is not enabled,
the device outputs data from sequential addresses without regard to burst boundaries;
the internal address wraps to 000000h if the device is read past the last address.
