2.5 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 uti-
lized 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.
