additional sector erase commands. To ensure the command is accepted, the sys-
tem 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 be accepted. Table 6 shows the outputs for DQ3.
Notes:
1. DQ5 switches to 1 when an Embedded Program or Embedded Erase operation exceeds the maximum timing limits.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further
details.
