Auto Address Increment (AAI)
Block Protection (BP3,BP2, BP1, BP0)
Block Protection Lock-Down (BPL)
The Auto Address Increment Programming-Status bit provides status on whether the device is in Auto
Address Increment (AAI) programming mode or Byte-Program mode. The default at power up is Byte-
Program mode.
The Block-Protection (BP3, BP2, BP1, BP0) bits define the size of the memory area, as defined 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-Protec-
tion bits are all 0. After power-up, BP3, BP2, BP1 and BP0 are set to 1.
WP# pin driven low (V
prevents any further alteration of the BPL, BP3, BP2, BP1, and BP0 bits. When the WP# pin is driven
