  • Control system for controlling electronic circuit, and signal relaying apparatus
    Patent number: 9111052
    Abstract: A bus interface receives, via a bus, a control signal for controlling an electronic circuit, and outputs a signal corresponding to the received control signal to the electronic circuit. A signal maintaining circuit maintains the value of the signal to be output from the bus interface to the electronic circuit in accordance with an instruction from a reset control circuit. When the bus becomes unusable due to termination of operations of the control device or the like, the reset control circuit causes the signal maintaining circuit to maintain the value of the output signal to the electronic circuit, and subsequently resets the bus interface so as to restore the bus.
