WE32K32-XXX
DATA POLLING
The WE32K32-XXX offers a data polling feature which allows a
faster method of writing to the device. Figure 8 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.

read cycle timings.
