To reliably detect a communication error status and to resolve the communication error status when reliably recovered from the error status. A count value is changed into one of up and down directions when a communication error is detected by a communication error determination unit, the count value is changed into the other direction of the up and down directions when communication being normal is detected by the communication error determination unit, a communication error status is output when the count value becomes a first threshold value, and the communication error status is resolved when the count value becomes a second threshold value different from the first threshold value.
