Figure 5-4 Timing Chart for the Write -> Write Operation
• Setting of the W05/W04 bits of the AWR register enables 0-3 write cycles to be inserted.
• After all of the write cycles, recovery cycles are generated.
• Write recovery cycles are also generated if write access is divided into phases for access with a bus width
wider than that specified.
