DATA POLLING
The module offers a data polling feature which allows a
faster method of writing to the device. Figure 6 shows the
timing diagram for this function. During a word or page
write cycle, an attempted read of the last word written will
result in the complement of the written data on I/O7 and
I/O15. 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.
