System Interface Using CE don’t-care.
For an easier system interface, CE may be inactive during the data-loading or sequential data-reading as shown below. The internal
528byte page registers are utilized as seperate buffers for this operation and the system design gets more flexible. In addition, for
voice or audio applications which use slow cycle time on the order of u-seconds, de-activating CE during the data-loading and read-
ing would provide significant savings in power consumption.
