Data Protection
In the event the user wants to deactivate the software
data protection feature for testing or reprogramming in
an EEPROM programmer, the following six step algo-
rithm will reset the internal protection circuit. After t
WC
,
the X28HC64 will be in standard operating mode.
Note:
Once initiated, the sequence of write operations
should not be interrupted.
