<p>PURPOSE:To shorten the waiting time, by providing a program loading switch for a service processor and an FF which stores the fact that the application of a power supply is over and then referring to the FF when the program is loaded again. CONSTITUTION:A power-on skip FF21 is provided at a power supply controlling part (not shown in the diaphragm). The reset conditions 1 are supplied 24 just once when the power supply of a service processor SVP is applied. Then the set conditions of the FF21 are supplied 25 when the power supply is applied for a processor. A gate 22 which puts the output data of the FF21 on a muCPU data bus 11 is gated by a signal 23 which decoded 26 a muCPU address bus 10. The SVP loads a program with application of a power supply. The inside of the SVP is checked by the loaded program. Then the procedure proceeds to a power supply application program of the processor main body. In this case, the power supply application sequence is skipped after checking the FF21 and then detecting the application of the power supply. In such a way, the waiting time can be shortened.</p> |
