<p><P>PROBLEM TO BE SOLVED: To count a time width being a data length of serial data, by a clock signal to easily detect normality/abnormality of the serial data by this time width. <P>SOLUTION: A data communication method and device input serial data (1) to a data reception detection circuit (11) to detect a start position (1a) and a stop position (1b) of the serial data (1) and detect a time width (13a) between them by a clock signal (12a) and use the time width (13a) to judge whether the serial data (1) is normal/abnormal. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
