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.
