C.2
The device is delivered with the second section of the extended memory block ‘customer lockable’: bits
DQ7 and DQ6 are set to '1' and '0' respectively. It is up to the customer to program and protect this
section of the extended memory block but care must be taken because the protection is not reversible.
This section can be protected by setting the extended memory block protection bit, DQ0, to ‘0’.
Bit DQ6 of the extended block protection indicator is automatically set to '1' to indicate that the second
section of the extended memory block is customer locked.
Once the extended memory block is programmed and protected, the Exit Extended Block command must
be issued to exit the extended block mode and return the device to read mode.
