Note:  
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 SR7 and SR6 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 BLOCK UNLOCK operations, re-  
sume the ERASE operation using the ERASE RESUME command.  
Note:  
A BLOCK LOCK SETUP command followed by any command other than BLOCK LOCK,  
BLOCK UNLOCK, or BLOCK LOCK DOWN produces a command sequence error and  
set SR4 and SR5. If a command sequence error occurs during an erase suspend, SR4 and  
SR5 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 op-  
eration, possible erase errors may be masked by the command sequence error.  
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 re-  
sumed. BLOCK LOCK operations cannot occur during a program suspend.
