Protection
Regardless of whether the device has previously been
protected or not, once the software data protection
algorithm is used and data has been written, the X28C64
will automatically disable further writes unless another
command is issued to cancel it. If no further commands
are issued the X28C64 will be write protected during
power-down and after any subsequent power-up.
Note:
Once nitiated, he sequence of write operations
should not be interrupted.
