摘要： An integrated circuit device having a send/receive macro for serially transferring addresses and data to or from an external device via a serial transfer bus, the integrated circuit device includes: a CPU for performing predetermined processing. The send/receive macro includes a send/receive buffer accessed by the CPU, for storing a plurality of units of data to be transmitted or received over the serial transfer bus; an acknowledge detection unit for detecting a data acknowledge signal transmitted from a receiving device in response to transmission of predetermined units of data; and a data send unit for transmitting data stored in the send/receive buffer, in response to detection of the data acknowledge signal by the acknowledge detection unit, without generating any interrupt to the CPU. And the acknowledge signal detection unit generates a data acknowledge signal non-detection interrupt to the CPU if the acknowledge detection unit does not detect a data acknowledge signal transmitted from the receiving device in response to transmission of the predetermined units of data.
