6.3.3 BP1, BP0 bits
The Block Protect (BP1, BP0) bits are non-volatile. They define the size of the area to be
software protected against Write instructions. These bits are written with the Write Status
Register (WRSR) instruction. When one or both of the Block Protect (BP1, BP0) bits is set to
1, the relevant memory area (as defined in
Table 3: Write-protected block size) becomes
protected against Write (WRITE) instructions. The Block Protect (BP1, BP0) bits can be
written provided that the Hardware Protected mode has not been set.
