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.
See the following for more information:
Table 7.17
, shows the outputs for Data# Polling on DQ7.

Notes:
1) DQ6 is toggling if Read2 DQ6 does not equal Read3 DQ6.
2) DQ2 is toggling if Read2 DQ2 does not equal Read3 DQ2.
3) May be due to an attempt to program a 0 to 1. Use the RESET
command to exit operation.
4) Write buffer error if DQ1 of last read =1.
5) Invalid state, use RESET command to exit operation.
6) Valid data is the data that is intended to be programmed or all 1's for
an erase operation.
7) Data polling algorithm valid for all operations except advanced sector
protection.
