WE32K32-XXX
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
on D7 (for each chip.) Once the write cycle has been
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.
