Block Protection (BP2, BP1, BP0)
The Block-Protection (BP2, BP1, BP0) bits define the size of the
memory area, as defined in Table 3, to be software protected
against any memory Write (Program or Erase) operations. The
Write Status Register (WRSR) instruction is used to program the
BP2, BP1, BP0 bits as long as WP is high or the 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 to 0.
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 TB, 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.
