System Interface Using CE don’t-care.
For an easier system interface, CE may be inactive during the data-loading or serial access as shown below. The internal
2112byte(X8 device) or 1056word(X16 device) data registers are utilized as separate 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-activat-
ing CE during the data-loading and serial access would provide significant savings in power consumption.
