  • Advanced data link controller having a plurality of multi-bit status registers
    Patent number: 4368512
    Abstract: A bit-oriented data link controller provides the interface between a microcomputer or terminal and a data communications link. The data link controller is capable of accommodating the three most commonly available bit-oriented data link control protocols, namely SDLC, HDLC, and ADCCP. The data link controller provides the data communications interface for both primary and secondary stations in stand-alone, polling, and loop configurations.
    Type: Grant
    Filed: March 21, 1980
    Date of Patent: January 11, 1983
    Assignee: Motorola, Inc.
    Inventors: Shikun Kyu, Edward C. Hepworth

  • Frequency divider circuit with selectable integer/non-integer division
    Patent number: 4193037
    Abstract: A divide circuit is provided for dividing an input signal of frequency N by the quantity M+0.5, where N is any positive number and M is an integer. In one embodiment a clock signal operating at a frequency of 3.5 megahertz is divided by 3.5, yielding an output signal of 1 megahertz. Additional logic means may be provided responsive to a control signal for dividing the input signal by the quantity M+1 for a given state of the control signal.
