Sector-locking Registers for AT49LW080
Function of Sector-locking Bits
Function
Reserved
Read Lock
1 = Prevents read operations in the sector where set.
0 = Normal operation for reads in the sector where clear. This is the default state.
Lock-down
1 = Prevents further set or clear operations to the Write Lock and Read Lock bits. Lock-down can only be set, but
not cleared. The sector will remain locked-down until reset (with RST or INIT), or until the device is power-cycled.
0 = Normal operation for Write Lock and Read Lock bits altering in the sector where clear. This is the default state.
Write Lock
1 = Prevents program or erase operations in the sector where set. This is the default state.
0 = Normal operation for programming and erase in the sector where clear.
