Extended Memory Block
C.2
The device is delivered with the second section of the Extended 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 Block but care must be taken because the protection is not reversible.
There are three ways of protecting this section:
Bit DQ6 of the Extended Block Protection Indicator is automatically set to '1' to indicate that the second
section of the Extended Block is Customer Locked.
Once the Extended 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.
