On Xicor’s X9312, X9C102/103/104/503, X9313,X9314, and X9316 XDCPs, the INC and CS pins serve to define the mode of operation. The signals are also NORed together to generate an enable signal for the internal wiper decoder as shown in Figure 1. Casual treatment of these control signals on power-up can lead to inadvertent store operations, “walking wipers” and other unexpected results.
