Abstract

PURPOSE: To make it possible to control receiving/transmission of various data transfer speeds in dne communication control module.
CONSTITUTION: In an initial state, processor 13 is controlled by firmware of ROM 14, and interprets commands of a central processing unit (arithmetic control unit and main memory), and reads and stores firmware data from the main memory into RAM 15. After that, the communication control module is mainly controlled by firmware of RAM 15. Firmware in RAM 15 can set the synchronous system of receiving/transmission by controlling URTLSI 17 as well as controls the transmission procedures. Further, various transmission clocks can be generated, and also, the transmission speed can be freely controlled by firmware, so that it is possible to control receiving/transmission of various data transmission speeds in one communication module.
