摘要:
An input/output device controller supplies power to a PC card in a secure manner. A PC card is a device that is loaded into a slot of a personal computer. The input/output device controller, which permits an information processing apparatus to communicate with an input/output device, operates in a manner so that when an abnormality is detected in the supply of operating power to the PC card, the detection result is reported to the personal computer. When an abnormality in the supply of operating power to the PC card is detected, the output of a driver for the PC card is halted so as to prevent the destruction of the internal circuitry of the PC card due to latch-up problems.
