Notes:
DQ7
DATA Polling: indicates the P/E status check during Program or Erase, and on completion before checking bits DQ5
for Program or Erase Success.
DQ6 Toggle Bit: remains at constant level when P/E operations are complete or erase suspend is acknowledged.
Successive reads output complementary data on DQ6 while programming or Erase operation are on-going.
DQ5 Error Bit: set to “1” if failure in programming or erase
DQ3 Sector Erase Command Timeout Bit: Operation has started. Only possible command is Erase suspend (ES).
DQ2 Toggle Bit: indicates the Erase status and allows identification of the erased Sector.
