Communication controller for controlling multi-channel multiplex communication and having channel selection functions and memory for storing communication control data for each channel

摘要

Multiplexed data lines are separated and data lines are multiplexed by a channel number obtained. The memory for storing control/condition information and transmission/reception data for each channel is provided as a periphery of the communication controller and the communication processing unit processes data so that past information is read, modified and re-stored sequentially each time a channel number is input.
