PURPOSE:To eliminate the need for stopping the transmission even in the course of receiving the data from an external equipment and to instantaneously update the data by using plural RAMs and formatting the contents of a ROM in the RAM. CONSTITUTION:From a ROM 1 in which information is preserved, the total frame number is read out and the data quantity is calculated, and by its portion, the data is transferred from the ROM 1 to a RAM 4. Also, by adding a synchronous pattern to the head of each frame, the contents of the RAM 4 are matched with a transmission format. Finally, the total frame number is written in a register, and transmission is started. |
