Abstract: PURPOSE:To mitigate the peak of a character processing time, by storing the transmission data from a communication control section to a first-in first-out shift memory sequentially and transmitting the content to a line in the bit transmission speed. CONSTITUTION:A transmission character from a communication control section LC is received at a transmission buffer register BFR and given to a shift register SFR, separated in bit serial and transmitted to a first-in first-out shift memory FIFO. The transmission data stored in the FIFO memory 1 is transferred to a memory 2 while waiting for the vacancy of the memory 2. Afterwards, this transmission data is moved to a memory (n) of the FIFO with the same operation. On the other hand, the content of the FIFO is transmitted to the line with a timing synchronized with the bit transmission speed of the line with the control of the CNT of the transmission control circuit. As a result, the temporary peak value of the character processing time of the communication control section can be mitigated.
