Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asyn-
chronously with DQ6-DQ0 while Output Enable (OE#) is asserted low. That is, the device may
change from providing status information to valid data on DQ7. Depending on when the system
samples the DQ7 output, it may read the status or valid data. Even if the device has completed
the program or erase operation and DQ7 has valid data, the data outputs on DQ6-DQ0 may be
still invalid. Valid data on DQ7-D00 appears on successive read cycles.
