ABSTRACT:
A method and apparatus for generating a divisor having a variable value for real time calculations. A microprocessor's time base register is used to generate the divisor. All interrupts and refreshes are disabled on the microprocessor before calculating the divisor. The microprocessor's time base register is cleared and allowed to count the number of clock ticks in a one second interval. The time base register is read and the value used as a divisor for real time calculations.
