To perform erase or programming, be sure to do one of
the following.
By executing the read lock bit status command, verify
that the lock of the target block is invalid.
Set the lock bit invalidity select bit to “1” to invalidate
the lock.
When the block erase or programming is performed with
the lock valid, the erase status bit (SR.5) and program-
ming status bit (SR.4) are set to “1” (terminated by error).
