14.8

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.

14.9

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.
