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.
WP
is high or the
Block Protection Lock-Down (BPL)
WP
pin driven low (V
IL
), enables the Block-Protection
-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
WP
pin is driven high (V
IH
), the BPL bit has no effect and its
value is “Don’t Care”. After power-up, the BPL bit is reset to 0.
