<p>PURPOSE:To provide the microcomputer which can store a correct execution history especially applied for a development supporting device. CONSTITUTION:This microcomputer is provided with an external input/output interface part 104 for converting the voltage threshold value level of a developing device connected through an external input/output terminal group 108 to a voltage level judged by an internal CPU part 102 and to out put it, and an input/output control part 103 for controlling the input/output of an input/output execution history signal group 118 with an execution history storage circuit connected through a terminal group 109 for external input/output execution history and controlling the exchange of signals with the internal CPU part 102 and the exchange of signals with the external input/output interface part 104, a prescribed first power source is supplied through a power supply terminal 106 to the external input/output interface part 104, and a second power source outputted from the development supporting device is supplied through a power supply terminal 105 to the CPU part 102 and the input/output control part 103.</p> |
