NOTE:
1. The burst wrap bit (RCR.3) determines whether 4- or 8-word burst-accesses wrap within the burst-length boundary or
whether they cross word-length boundaries to perform linear accesses.
In the no-wrap mode (RCR.3=1), the device operates similar to continuous linear burst mode but consumes less power
during 4- and 8-word bursts.
Synchronous burst mode will be available for future device.
