Block Protection (BP2, BP1, BP0)
The Block-Protection (BP2, BP1, BP0) bits define the size of the
memory area, as defined in Table2 to be software protected
against any memory Write (Program or Erase) operations. The
Write-Status-Register (WRSR) instruction is used to program the
BP2, P1, BP0 bits as long as
Block-Protection-Look (BPL) bit is 0. Chip-Erase can only be
executed if Block-Protection bits are all 0. After power-up, BP2,
BP1 and BP0 are set to1.

Block Protection Lock-Down (BPL)
-Lock-Down (BPL) bit. When BPL is set to 1, it prevents any
further alteration of the BPL, BP2, BP1, and BP0 bits. When the
value is “Don’t Care”. After power-up, the BPL bit is reset to 0.
