Backup Registers
Restore OCS Data:
When initiated, this will allow the user to manually copy the backed-up data from the onboard
flash memory 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 memory 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.

Restore OCS Data
%SR164.3 is set to the value of 1 only when an automatic restore operation is performed - not
on a manual one. This bit is reset to the value of 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.
