Figure 7. Write Sequence for
Software Data Protection
Regardless of whether the device has previously been
protected or not, once the software data protected
algorithm is used and data has been written, the device
will automatically disable further writes unless another
command is issued to cancel it. If no further commands
are issued the device will be write protected during
power-down and after any subsequent power-up.
