Inf o rmation
After the sector erase command is written, the system should read the status of DQ7 (Data#
Polling) or DQ6 (Toggle Bit I) to ensure that the device has accepted the command sequence,
and then read DQ3. If DQ3 is “1,” the Embedded Erase algorithm has begun; all further com-
mands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is “0,”
the device will accept additional sector erase commands. To ensure the command has been ac-
cepted, the system software should check the status of DQ3 prior to and following each
subsequent sector erase command. If DQ3 is high on the second status check, the last command
might not have been accepted.
Table 23 shows the status of DQ3 relative to the other status bits.
Notes:
1. DQ5 switches to ‘1’ when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits.
Refer to the section on DQ5 for more information.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further
details.
3. When reading write operation status bits, the system must always provide the bank address where the Embedded
Algorithm is in progress. The device outputs array data if the system addresses a non-busy bank.
