Each of the blocks in Figure 32.17 have a nonvolatile lock bit that specifies protection (block lock) against
erasing/writing. A block is locked (writing “0” for the lock bit) with the lock bit program command. Also, the
lock bit of any block can be read with the read lock bit status command.
Block lock disable/enable is determined by the status of the lock bit itself and execution status of the lock
bit disable and lock enable bit commands.

was erased is set to “1” (unlocked) after erasing, therefore the block is actually unlocked with the
lock bit.
