<p><P>PROBLEM TO BE SOLVED: To provide a communication device capable of guaranteeing a time of data transmitted to a plurality of peripheral circuits, without performing complicated priority control. <P>SOLUTION: A communication device 100 includes: a transmission register 35 in which transmission data is stored; transmission destination specification means 34 for specifying one transmission destination from a plurality of transmission destinations; transmission control means 33 for serially transmitting the transmission data to the transmission destination; transmission data buffers 36, 39 for storing transmission data waiting for transmission; transmission data control means 40 for overwriting the transmission data stored in the transmission register on the transmission data stored in the transmission data buffers when the transmission destinations of the transmission data stored in the transmission register and the transmission data stored in the transmission data buffers are identical. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
