Notes
1. Clearing the FO_ON bit will not disable the FOx outputs for the case a failure occurred which triggered the FOx
outputs. In this case the FOx outputs have to be disabled by clearing the FAILURE bit.
If the FO_ON bit is set by the software then it will be cleared by the SBC after SBC Restart Mode was entered
and the FOx outputs will be disabled. See also Chapter 12 for FOx activation and deactivation.
