Software Protected Mode (SPM): The Block Protect (BP2, BP1, BP0 for uniform 256 KB sector product:
BP3, BP2, BP1, BP0 for uniform 64 KB sector product) bits define the section of the memory array that can
be read but not programmed or erased.
that are defined by Status Register bits BP2:BP0 for uniform 256 KB sector product, BP3:BP0 for uniform
64 KB sector product).
Hardware Protected Mode (HPM): The Write Protect (WP#/ACC) input and the Status Register Write
Disable (SRWD) bit together provide write protection.
Clock Pulse Count: The device verifies that all program, erase, and Write Status Register commands
consist of a clock pulse count that is a multiple of eight before executing them.
