DEVICE FOR TRANSMITTING INTERRUPT MODE MESSAGE OF WIRELESS LOCAL LOOP OUTDOOR TYPE TERMINAL

摘要

PURPOSE: A device for transmitting an interrupt mode message of a wireless local loop outdoor type terminal is provided to exchange a message between processes without extra hardware for transmitting an interrupt signal between an indoor unit and an outdoor unit. CONSTITUTION: A transmission message register(411) records a message to be transmitted by a transmitting side processor. An interrupt state managing part(412) informs a receiving side processor that data are recorded at the transmission message register(411). A temporary register(414) is provided for loading data to load the message at a time slot. A timing control part(413) moves the data of the transmission message register(411) to the temporary register(414) or releases an interrupt state and controls timing for loading the data at the decided time slot. A time slot assigning part(415) loads the data at the decided time slot. An address decoding part(416) accesses the decided address when the transmission message register(411) or the interrupt state is observed. A received message register(421) stores the received message. An interrupt generating part(422) informs that the message is received. An interrupt release signal generating part(423) releases the interrupt after terminating the interrupt work. A timing control part(424) receives the decided time slot or controls timing related part. A temporary load register(425) loads the received data temporarily. A time slot extracting part(426) extracts the decided time slot. An address decoding part(427) decides an address reading the received message.
