EEPROM DATA POLLING
The WSE128K16-XXX offers a data polling feature for
the EEPROM which allows a faster method of writing to
the device. Figure 11 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.
