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(x8 device), 264word(x16 device) 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 reading would provide significant savings in power consumption.
