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 2,112byte
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 µ-seconds, de-activating CE during the data-loading and serial access
would provide significant savings in power consumption.
