Data Protection Modes
Spansion SPI Flash memory devices provide the following data protection methods:
BP2
The Write Enable (WREN) command: Must be written prior to any command that modifies data. The
WREN command sets the Write Enable Latch (WEL) bit. The WEL bit resets (disables writes) on power-up
or after the device completes the following commands:
Software Protected Mode (SPM): The Block Protect (BP2, BP1, BP0) bits define the section of the
memory array that can be read but not programmed or erased.
ranges of protected areas that are defined by Status Register bits BP2:BP0.
Hardware Protected Mode (HPM): The Write Protect (W#) 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.
