4.9.5 Sector Locking while Erase Suspend
The sector lock status can be performed during an erase
suspend by using standard locking command sequences
to unlock, lock, or lock-down a sector.
In order to change sector locking during an erase opera-
tion, the write erase suspend command (B0H) is placed
first; then check the status register until it is shown that
the actual erase operation has been suspended. Subse-
quent writing the desired lock command sequence to a
sector and the lock status will be changed. When com-
pleting any desired lock, read or program operation, re-
sume the erase operation with the Erase Resume Com-
mand (D0H).
If a sector is locked or locked-down during the same
4.9.6 Status Register Error Checking
The operation of locking system for this device can be
used the term "state (X,Y,Z)" to specify locking status,
where X=value of WP, Y=bit DQ1 of the sector lock sta-
tus register, and Z=bit DQ0 of the sector lock status
register. DQ0 indicates if a sector is locked (1) or un-
locked (0). DQ1 indicates if a sector has been locked-
down(1) or not (0).

Table 5. Sector Locking State Transitions
sector is being placed in erase suspend, the locking sta-
tus bits will be changed immediately, but when the erase
is resumed, the erase operation will complete.
Locking operation cannot be performed during a program
suspend.
Note:
At power-up or device reset, all sectors default to locked state (001) (if WP=0).
Holding WP=0 is the recommended default.
