... Byte write capability has been included in order to greatly simplify Read/Modify/Write sequences, which can be reduced to simple byte write operations. Because the CY7C1354V25/56V25 is a common I/O device, data should not be driven into the device while the outputs are active. The Output Enable (OE) can be deasserted HIGH be- fore presenting data to the DQ and DP (DQ CY7C1354V25 & ...
