Restore OCS Data:
When initiated, this will allow the user to manually copy the backed up data from the onboard FLASH to
the Battery-Backed RAM.
A restore operation will be automatically initiated if a backup has been previously created and on power-
up the Battery-Backed RAM registers fail their check.
The following process will be followed for restoring data:
• The controller will be placed in IDLE mode.
• Data will be copied from onboard FLASH to OCS Battery-Backed RAM
• The controller will reset.
• The controller will be put in RUN mode if the AutoRun setting is ‘Yes’ else it will remain in IDLE
mode.
%SR164.3 is set to 1 only when an automatic restore operation is performed - not on a manual one. This
bit is reset to 0 when a new backup is created.
Restoring of data can be manually performed by selecting RESTORE option from the Backup / Restore
Data menu. This will cause the controller to reset.

Clear Backup Data:
