Clock Edge (RCR[6])
Configuring the valid clock edge enables a flexible memory interface to a wide range of
burst CPUs. Clock configuration sets the device to start a burst cycle, output data, and
assert WAIT on the clock’s rising or falling edge.
Burst Wrap (RCR[3])
The burst wrap bit determines whether 4-, 8-, or 16-word burst accesses wrap within
the burst-length boundary or whether they cross word-length boundaries to perform
linear accesses. No-wrap mode (RCR[3]=1) enables WAIT to hold off the system
processor, as it does in the continuous burst mode, until valid data is available. In no-
wrap mode (RCR[3]=0), the device operates similarly to continuous linear burst mode
but consumes less power during 4-, 8-, or 16-word bursts.
For example, if RCR[3]=0 (wrap mode) and RCR[2:0] = 1h (4-word burst), possible
linear burst sequences are 0-1-2-3, 1-2-3-0, 2-3-0-1, 3-0-1-2.
