Software Data Protection
The PUMA 68E4001 can be automatically protected during power-up and power-down without the need for external
circuits by employing the software data protect feature. The internal software data protection circuit is enabled after
the first write operation utilizing the software algorithm. This circuit is nonvolatile and will remain set for the life of
the device unless the reset command is issued.
Once the software protection is enabled, the PUMA 68E4001 is also protected against inadvertent and accidental
writes in that, the software algorithm must be issued prior to writing additional data to the device.
