TIMER ERROR COMPENSATION METHOD, CAPABLE OF PERIODICALLY COMPENSATING THE ERROR ACCUMULATED BETWEEN TIC GENERATED IN A TIMER AND A SYSTEM TIC

摘要

PURPOSE: A timer error compensation method is provided to compensate the accumulated error of generated tic with a certain periodicity using a clock signal having a predetermined frequency.;CONSTITUTION: A first counter counts the clock signal of 32768Hz(S21). A tic generator compares the reference value and a clock signal counting value to determine the clock signal counting value(S22). The first counter is reset in response to a reset signal received by a controller. The tic generator generates the tic.;COPYRIGHT KIPO 2011
