After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6 (Tog-
gle Bit I) to ensure that the device accepted the command sequence, and then reads DQ3. If DQ3 is “1,” the
Embedded Erase algorithm started; all further commands (except Erase Suspend) are ignored until the erase op-
eration is complete. If DQ3 is “0,” the device accepts additional sector erase commands. To ensure the command
was accepted, 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 37 on page 120
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” on page 30
for more details.
Table 37. Write Operation Status
Notes:
1. DQ5 switches to ‘1’ when an Embedded Program, Embedded Erase, or Write-to-Buffer operation 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. The Data# Polling algorithm should be used to monitor the last loaded write-buffer address location.
4. DQ1 switches to ‘1’ when the device aborts the write-to-buffer operation
