摘要：
To aim to provide an interface circuit that supports both a single-ended method and a differential method as a transmission method, and one of pairs of input terminals for a differential signal is shared to input/output a single-ended signal.A differential signal receiving circuit that receives a differential signal input through the pair of shared terminals is activated when a differential signal is input to a pair of dedicated input terminals for a differential signal, which is different from the pair of shared terminals. After the differential signal receiving circuit is activated, the active state is maintained by a built-in controller.Accordingly, the activation of the differential signal receiving circuit that receives a differential signal input through the shared terminals is controlled by controlling the differential signal input through the pair of dedicated input terminals, and furthermore, the possibility that the differential signal receiving circuit becomes inactive at an unexpected timing is reduced to a low level.
