... WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of four levels of protec- tion for the Pm25LV010. The Pm25LV010 is divided into four blocks where the top quarter (1/4), top half (1/2), or all of the memory blocks can be protected (locked out) from write. The Pm25LV512 is divided into 2 blocks where all of the memory blocks can be protected (locked out) from write ...
