Verify extended memory block protection indicator
The extended memory block is either factory locked or customer lockable.
The protection status of the extended memory block (factory locked or customer lockable)
can be accessed by reading the extended memory block protection indicator. It can be read
in auto select mode using either the programmer (see

Verify block protection status
The protection status of a block can be directly accessed by performing a read operation
with control signals and addresses set as shown in
If the block is protected, then 01h (in x 8 mode) is output on data input/outputs DQ0-DQ7,
otherwise 00h is output.
