4. An Enter command sequence must be issued prior to any operation. It disables read and write operations from and to block 0. Read and write operations from any

other block are allowed.

5. DATA = Lock Register content.

6. Only one portion of password can be programmed or read by each Password Program command.

8. Protected and unprotected states correspond to 00 and 01, respectively.

9. The Clear all NVPBs command programs all NVPBs before erasure in order to prevent the over-erasure of previously cleared Non-volatile Modify Protection bits.
