Handling Errors that Occur within a Stall Detector

In this design, a stall mechanism uses an interrupt protocol wherein the initiator sends an interrupt signal to the receiver. If the interrupt logic in the initiator fails, (solid interrupt request), the receiver must threshold the requests. If the threshold is reached, the receiver will set an external signal of the condition so a repair action can be scheduled. The receiver then has a mechanism to mask the initiator's interrupt and associated logic from causing any further error conditions to the receiver. The initiator then continues its function without the stall detect during the interim period until the repair is made.
