DQ3: Sector Erase Timer
After writing a sector erase command sequence, the system may read DQ3 to de-
termine whether or not erasure has begun. (The sector erase timer does not
apply to the chip erase command.) If additional sectors are selected for erasure,
the entire time-out also applies after each additional sector erase command.
When the time-out period is complete, DQ3 switches from a “0” to a “1.” If the
time between additional sector erase commands from the system can be as-
sumed to be less than 50 μs, the system need not monitor DQ3. See also the
Sector Erase Command Sequence section.
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 commands (except Erase Suspend) are ignored
until the erase operation is complete. If DQ3 is “0,” the device will accept addi-
tional sector erase commands. To ensure the command has been accepted, the
system software should check the status of DQ3 prior to and following each sub-
sequent sector erase command. If DQ3 is high on the second status check, the
last command might not have been accepted.
Table
12
shows the status of DQ3 relative to the other status bits.
DQ1: Write-to-Buffer Abort
DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these
conditions DQ1 produces a “1”. The system must issue the Write-to-Buffer-Abort-
Reset command sequence to return the device to reading array data. See Write
Buffer section for more details.
