<p><P>PROBLEM TO BE SOLVED: To maintain a stable receiving operation without generating slip of data for over 24 hours and 365 days. <P>SOLUTION: A clock frequency of a read timing of a reception buffer 6 by setting an interval for circulating an address of the reception buffer 6 as equivalent, inserting and drawing out the prescribed number of pulses by very circulation of the address of the reception buffer 6 is varied. Thus, the clock frequency of the read timing is controlled so that a writing position and a reading position to the reception buffer 6 constantly hold fixed intervals. <P>COPYRIGHT: (C)2004,JPO</p> |
