Abstract

PURPOSE: To detect a CPU fault at the sender side from the reception side without transferring a CPU faulty alarm through other line by transferring a fixed pulse pattern as a serial data output at CPU fault.
CONSTITUTION: A fault detection circuit 3 monitoring the state of a CPU 1 outputs a CPU fault alarm signal to a pulse pattern generating circuit 4 and a selection circuit 5 at CPU fault. The pulse pattern generating circuit 4 is started by a CPU fault alarm signal, a pulse pattern representing the CU fault alarm is outputted and the output becomes other input to the selection circuit 5. The selection circuit 5 receiving a CPU fault alarm signal outputs and selects a pulse pattern from the pulse pattern generating circuit 4 and gives an output to the reception side.
