Method for implementing a control channel in a system of circumvention and recovery

A method of operating a multi-function system having a plurality of peripherals having various levels of susceptibility to events, the method comprising:

• detecting an event;
• placing each peripheral susceptible to the event into safe mode via a dedicated control interface based at least in part on the susceptibility of the peripheral to the event;
• detecting the end of the event;
• and
• implementing restoring procedures on each peripheral susceptible to the event via at least one of the dedicated control interface and a dedicated communication interface to restore each peripheral to normal operations after the detection of the end of the event.

A controller for a multi-function system, the controller comprising:

• at least one event signal port configured to receive a event signal from at least one event detector;
• a dedicated control read channel port configured to receive signals from a plurality of peripherals via a dedicated control interface;
• a dedicated control write channel port configured to send control signals to the plurality of peripherals via the dedicated control interface;
• at least one dedicated clock for transmit and receive;
• and
• a first processor in communication with the at least one event signal port via a dedicated communication interface, the dedicated control interface, the dedicated control read channel port and the dedicated control write channel port, the first processor configured to process event signals and to generate control signals to the peripherals based on received event signals, wherein the control signals implement a circumvention process in each peripheral based on the peripherals susceptibility of the event detected and implements a recovery process when the event is over.
