Spansion SPI Flash memory devices provide the following data protection methods:
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.
and address ranges of protected areas that are defined by Status Register bits BP2:BP0.
Hardware Protected Mode (HPM): The Write Protect (W#/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 Register commands consist of
a clock pulse count that is a multiple of eight before executing them.
