8.1.1
Enable Sector Protection
Sectors specified for protection in the Sector Protection Register can be protected from program and erase
operations by issuing the Enable Sector Protection command. To enable the sector protection, a 4-byte command
sequence of 3Dh, 2Ah, 7Fh, and A9h must be clocked into the device. After the last bit of the opcode sequence
has been clocked in, the CS pin must be deasserted to enable the Sector Protection.

8.1.2
Disable Sector Protection
To disable the sector protection, a 4-byte command sequence of 3Dh, 2Ah, 7Fh, and 9Ah must be clocked into
the device. After the last bit of the opcode sequence has been clocked in, the CS pin must be deasserted to
disable the sector protection.
