Protection operations during Erase Suspend

Changes to block protection status can be performed during an erase suspend by using the

standard protection command sequences to unprotect or protect a block. This is useful in

the case when another block needs to be updated while an erase operation is in progress.

To change block protection during an erase operation, first write the Erase Suspend

command, then check the Status Register until it indicates that the erase operation has

been suspended. Next write the desired Protect command sequence to a block and the

protection status will be changed. After completing any desired protect, read, or program

operations, resume the erase operation with the Erase Resume command.

If a block is protected during an erase suspend of the same block, the erase operation will

complete when the erase is resumed. Protection operations cannot be performed during a

program suspend.
