<p><P>PROBLEM TO BE SOLVED: To provide a computer system that stably starts up from a shut-down mode by securing a time period waiting for stabilization. <P>SOLUTION: The computer system is provided with: an interruption signal permitting circuit for setting a recovery factor for recovery from a shut-down mode by an interruption signal when a mode is shifted into the shut-down mode, permitting the interruption of the interruption signal, based on the recovery factor, in recovery from the shut-down mode, for the recovery from the shut-down mode; a voltage supply start time securing circuit for securing a predetermined power source start stabilization time triggered by a voltage supply start signal for permitting the interruption, which is outputted by the interruption permitting circuit, and then outputting an oscillation start signal in the recovery from the shut-down mode; and an oscillation stabilization waiting circuit for securing a predetermined oscillation start time triggered by an oscillation stabilization waiting determination signal, and then, outputting an instruction for allowing an oscillation circuit to supply a clock to the computer. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
