Abstract
PURPOSE: To obtain a high-accuracy timer circuit by providing the counter which counts the output signals of the oscillator up to the prescribed value and then grows the timer renewal start signals plus the counter which counts the timer renewal start signals in the prescribed frequencies.
CONSTITUTION: The pulse sent from oscillator 1 is converted into 2μs pulse via 4-step division 2 and differentiation 3 to advance 8-bit binary counter 4, Counter 4 is set to original value decimal 88 with counter 6 set to 01. When the count value of counter 4 reaches 255, the carry is given to renew the timer. Counter 6 changes to 10, and the lowest bit of counter 4 is set to the value of counter 6 before alteration to start counting again at 88 and then to generate the carry at 255. Counter 6 changes to 00, and the lowest bit of counter 4 is set to 1 before alteration of counter 6 to start counting from 89. Thus, the timer renewal period becomes 334μs twice in 3 times and becomes 332μs once with no accumulation of error.
