WP# Lock-Down Control for Selectable OTP Lock Blocks
Once the block has been permanently locked with OTP bit, WP# at VIH does not
override the lock down of the blocks those bits control.
Selectable OTP Locking Implementation Details
Clearing (write to “0”) any of the four Permanent Lock bits shall effectively cause the
following commands to fail with a block locking error when issued to their
corresponding blocks: Buffer Program command, Bit-Alterable Buffer Write command,
Word Program command, Bit-Alterable Word Write command, and Erase command. No
other commands shall be affected.
Programming the Permanent Lock bits or the Configuration Lock bit shall be done using
the Protection Register Programming command. As with all bits in the CFI/OTP space
once the Permanent Lock or the Configuration bits are programmed, they may not be
erased (set) again.
