Figure 16.3 – Backup Registers

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.

Figure 16.4 – Restore OCS Data

%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.
