摘要： A control processor has an output pattern generating circuit operating in cooperation with a free running timer, and a virtual OCR program for virtually realizing a large number of timer outputs by use of the output pattern generating circuit. Because more timer outputs than the actually incorporated timers are handled, the function of timer outputs is implemented with a higher degree of freedom and in a wider range of applications. For its enhanced function and availability, the control processor costs less.

摘要： In the particular embodiment of the invention described in the specification, a variable resistor is connected in potentiometer fashion to a DC power source and a time interval is selected according to the position of the movable contact. The ratio of the partial voltage provided by the movable contact to the full voltage applied to the resistor is determined and an oscillator signal target count for the selected time interval is computed from a count corresponding to the total voltage. The arrangement permits accurate time interval determination which is independent of variations in the supply voltage, variations in resistance value of the variable resistor, or environmental changes.
