Abstract:
1. An electronic control apparatus comprising: a control circuit for controlling a control object device; a communication driver for transforming signals applied thereto for communication between the control circuit and an external apparatus through a communication bus; a check circuit for checking whether the communication has started through the communication bus; a latch circuit for latching a communication start signal outputted from the check circuit; a power circuit for generating a power voltage, which is supplied to the control circuit in accordance with a control signal outputted from the control circuit or the communication start signal applied through the latch circuit; and a low voltage detection circuit for detecting fall of the power voltage below a predetermined threshold level, wherein the control circuit is reset and the check circuit is permitted to output the communication start signal, by the low voltage detection signal outputted from the low voltage detection circuit.
