<p><P>PROBLEM TO BE SOLVED: To provide a power source supply system programmable of power-on sequences which are different for every systems. <P>SOLUTION: In a processor LSI1, a power source for I/O are separated to two kinds, and one is a power source for a boot I/O 15, the other is a power source for I/O 13 of the system. When a battery 5 is mounted, only a power source 41 for core of the processor LSI1 and a power source 46 for boot I/O are set to ON, and an environment in which the processor LSI1, a memory 2, and an interface 101 between the processor LSI1 and PMLSI4 can operate is provided. The processor LSI1 sets the power-on sequence wanted as the whole system to a memory 47 for sequencer through the serial interface 101. After the power source turn on sequence is set, the processor LSI1 issues a command of reboot request to the PMLSI4. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
