Abstract
According to a synchronization method, a basic timing signal generation circuit generates a basic timing signal. A communication control circuit generates a first communication cycle timing signal, measures an input difference between the basic timing signal and a predetermined one of first communication cycle timing signals, divides a compensation value responsive to the input difference by the number of first communication cycle timing signals, adds up a value resulting from the division in a communication cycle, compensates for timing of generating the first communication cycle timing signal with timing equal to or greater than a predetermined value, and transmits timing compensation data to external equipment. The external equipment generates a second communication cycle timing signal, compensates for timing of generating the second communication cycle timing signal based on timing of receipt of the timing compensation data, and synchronizes with the first communication cycle timing signal.
