Figure 7. Write Sequence for Software
Data Protection
Regardless of whether the device has previously been
protected or not, once the software data protection
algorithm is used, the X28HC64 will automatically dis-
able further writes unless another command is issued
to deactivate it. If no further commands are issued the
X28HC64 will be write protected during power-down
and after any subsequent power-up.
Note:
Once initiated, the sequence of write operations
should not be interrupted.
