System sources connect to the SEC through the SSI. Each core has a dedicated SCI. The SFI provides fault action
connections to the rest of the system.

SEC Fault Interface (SFI)
The SFI manages fault events and associated actions. The fault management support provided in the SEC helps
satisfy the safety requirements of various applications. The SSI provides the highest priority pending source that is
enabled as a fault. The SFI captures this value and enables a countdown, and once the countdown expires, takes the
prescribed action.
Fault actions which can be configured, as shown in SFI Block Diagram, include
• Trigger Output
• System Reset
• Fault Output
• Computer Operating Properly (COP) mode
• Fault Mode
