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 D
7
(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.
