Read-Lock
1 = Prevents read operations in the block where set
0 = Normal operation for reads in the block 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 only can be set
but not clear. The block will remain lock-down until reset (with RST or
INIT
being Low), or until the device
is power-on reset.
0 = Normal operation for Write-Lock and Read-Lock bit altering in the block where clear. This is the default state.
Write-Lock
1 = Prevents program or erase operations in the block where set. This is the default state.
0 = Normal operation for programming and erase in the block where clear.
