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 is 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
completse when the erase is resumed. Protection operations cannot be performed during a
program suspend.
