DATA POLLING

The WE32K32-XXX offers a data polling feature which

allows a faster method of writing to the device. Figure 7

shows the timing diagram for this function. During a byte

or page write cycle, an attempted read of the last byte

written will result in the complement of the written data

completed, true data is valid on all outputs and the next

cycle may begin. Data polling may begin at any time during

the write cycle.
