Abstract
A microcomputer for functioning according to operation modes includes; a mode counter that counts the number of times of level change in a signal applied to a mode setting terminal; a mode decoder that decodes output data of the mode counter to output a mode signal, which represents one operation mode; a clock input terminal; a data terminal through which serial data is inputted synchronously with a serial clock signal applied to the clock input terminal; a serial-to-parallel conversion unit that converts the serial data into parallel data and stores the parallel data in an input data buffer; and a switching means that switches to a state that a CPU can access to the input data buffer in a test mode. In the test mode, test instruction data is capable of being inputted from an external circuit.
