If this time-out condition occurs during sector erase op-
eration, it specifies that a particular sector is bad and it
may not be reused. However, other sectors are still func-
tional and may be used for the program or erase opera-
tion. The device must be reset to use other sectors.
Write the Reset command sequence to the device, and
then execute program or erase command sequence. This
allows the system to continue to use the other active
sectors in the device.
If this time-out condition occurs during the chip erase
operation, it specifies that the entire chip is bad or com-
bination of sectors are bad.
TABLE 8. WRITE OPERATION STATUS
Note:
1. Q7 and Q2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
2. Q5 switches to '1' when an Auto Program or Auto Erase operation has exceeded the maximum timing limits.
3. Successive reads from the erasing or erase-suspend sector causes Q2 to toggle.
4. Reading from non-erase suspended sector address will indicate logic "1" at the Q2 bit.

If this time-out condition occurs during the byte program-
ming operation, it specifies that the entire sector con-
taining that byte is bad and this sector may not be re-
used, (other sectors are still functional and can be re-
used).
The time-out condition will not appear if a user tries to
program a non blank location without erasing. Please
note that this is not a device failure condition since the
device was incorrectly used.
