Data Sheet
Auto Address Increment (AAI)
The Auto Address Increment Programming-Status bit provides status on whether the device is in AAI
programming mode or Byte-Program mode. The default at power up is Byte-Program mode.
Block Protection (BP3,BP2, BP1, BP0)
The Block-Protection (BP3, BP2, BP1, BP0) bits define the size of the memory area, as shown in Table
4, to be software protected against any memory Write (Program or Erase) operation. The Write-Status-
Register (WRSR) instruction is used to program the BP3, BP2, BP1 and BP0 bits as long as WP# is
high or the Block-Protect-Lock (BPL) bit is 0. Chip-Erase can only be executed if Block-Protection bits
are all 0. After power-up, BP3, BP2, BP1 and BP0 are set to the defaults specified in Table 4.
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, BP3, 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.
