  • Timer unit and data processing apparatus including the same
    Patent number: 5218693
    Abstract: A digital timer unit employs a capture register and a save register. The capture register latches count data provided from a counter in accordance with a first edge of an event pulse. The save register latches count data of the capture register in accordance with a second edge of the event pulse while the capture register latches new count data provided from the timer. Data within the capture register and the save register after completion of the event pulse define a duration of an event pulse with a relatively small duration.

  • Timer unit and data processing apparatus including the same
    Patent number: 5058050
    Abstract: A micro computer has a free-running counter, a first capture register served with counted data from the free-running counter, and a second capture register which is selectively served with the data held in the first capture register or the counted data from the free-running counter. The second capture register works as a save register for the first capture register. This makes it possible to increase the precision of the timer unit in the micro computer, enabling the timer unit to find general applicability more extensively.
