or Lock-Down Block produces a command sequence error and set Status Register bits SR.4
and SR.5. If a command sequence error occurs during an erase suspend, SR.4 and SR.5
remains set, even after the erase operation is resumed. Unless the Status Register is cleared
using the Clear Status Register command before resuming the erase operation, possible erase
errors may be masked by the command sequence error.

Block Locking During Suspend
Block lock and unlock changes can be performed during an erase suspend. To change
block locking during an erase operation, first issue the Erase Suspend command.
Monitor the Status Register until SR.7 and SR.6 are set, indicating the device is
suspended and ready to accept another command.
Next, write the desired lock command sequence to a block, which changes the lock
state of that block. After completing block lock or unlock operations, resume the erase
operation using the Erase Resume command.
If a block is locked or locked-down during an erase suspend of the same block, the lock
status bits change immediately. However, the erase operation completes when it is
resumed. Block lock operations cannot occur during a program suspend. See
A, “Write State Machine” on page
