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.
