Claims

[Claims for Utility Model Registration] An S/P conversion unit that receives serial data from a transmission line and converts it into parallel data, a reception data buffer that temporarily stores at least one frame of this data, and a reception data buffer that adds parity to this stored data. a receiving section having a bus transmitting section for transmitting data to the internal bus; a transmitting data buffer for temporarily storing at least one frame of data received from the internal bus; and a CRC for adding a CRC to this one frame's worth of data.
generation means, a P/S that converts the generated parallel data into serial data and sends it to the transmission line;
A communication control device comprising a transmitting section having a converting section, comprising: a CRC check means for checking a CRC stored in the received data buffer; and a parity check means for checking parity stored in the transmitted data buffer. A communication control device characterized in that:
