ABSTRACT:
An I/o control gate array, a power supply controller, an EEPROM of a battery pack, a DS (docking station) controller, and an EEPROM of a docking station are connected to an I.sup.2 C serial BUS. This I.sup.2 C serial BUS and an ISA bus are connected by the I/O control gate array. The I/O control gate array incorporates a master control logic. Master arbitration between the power supply controller and the DS controller connected to the I.sup.2 C BUS is intensively controlled by arbitration circuitry of the I/O control gate array by using REQ# and GNT# lines of these masters.
