Data# Polling (DQ
Toggle Bits (DQ6 and DQ2)
When the SST39WF1601/1602 are in the internal Program operation, any attempt to read DQ
produce the complement of the true data. Once the Program operation is completed, DQ

Write operation, the remaining data outputs may still be invalid: valid data on the entire data bus will appear in
subsequent successive Read cycles after an interval of 1 µs. During internal Erase operation, any attempt
to read DQ
The Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation. For
Sector-, Block- or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or CE#)
pulse. See Figure 7 for Data# Polling timing diagram and Figure 21 for a flowchart.
During the internal Program or Erase operation, any consecutive attempts to read DQ
