<p>PURPOSE:To reduce the necessary area by including the dynamic action circuit into the semiconductor integrated circuit, at the same time reducing the power consumption of the stand-by action time. CONSTITUTION:In case the working power source is switched to the stand-by power source such as the battery or the like, stand-by timing generation circuit 8 is driven to start the stand-by action. And the latching is given through FF1- FF3 to IRQ', TC' and SC' of the external control signal in order to secure the immediate resetting to the normal action when the stand-by action is released. Then holding signal HOLD is delivered to hold each part. Furthermore, timing signals phi1-phi6 to be supplied to dynamic action circuit 6 are fixed at the specific levels to secure holding of the information due to the static action. To release the stand-by action, the latchig of the external control, the holding state and then the fixture of the timing signal are released respectively.</p> |
