<p>PURPOSE: To enable a CPU mode recognizing device and a digital processor to accurately recognize a CPU stop mode in an external file, etc. CONSTITUTION: The CPU mode recognizing device of the digital processor is provided with a clock signal supply circuit 6 which stops supply of a clock signal to a digital device 4 when a CPU 2 is set in the CPU stop mode. Further, the device is provided with a detecting circuit 8 which is connected to a clock signal supply circuit 6 for the CPU 2 and detects the clock signal supplied from the clock signal supply circuit 6 and a stop mode recognizing circuit 10 which is connected to the output of the detecting circuit 8 and outputs a CPU stop mode recognition signal unless the detecting circuit 8 outputs a detection signal within a previously set time.</p> |
