  • Operation mode transfer system and method
    Patent number: 6076119
    Abstract: An operation mode transfer system capable of solving a problem of a conventional system in that a processing load of a host computer cannot be reduced as long as a device is physically connected with the host computer because the host computer must carry out, even when the device is inoperative, the same communication processing as that performed when the device is operative. The present system connects a pullup resistor to a pullup power supply to set the device operative, and disconnects it from the pullup power supply to set the device inoperative, in response to the instructions from a CPU of the device.

  • Microcomputer having an output circuit with a resistor ladder
    Patent number: 5966086
    Abstract: A microcomputer includes an operation circuit for performing an operation using a reference voltage. A reference voltage input terminal receives the reference voltage from an external device. An output circuit outputs an output signal from the microcomputer to an external destination. The level of the output signal depends on the reference voltage input through the reference voltage input terminal.
