Abstract
A bus management node,has a register for channels in use REG,and a bus capacity register REG,Before starting the synchronous communication, each node,transmits a read-out command to the register for channels in use REG,and the register for channels in use REG,in order to read out their contents for ascertaining the number of the un-used channel and the residual capacity. If there is any un-used channel and any residual bus capacity, the node,transmits write commands to these registers REG,and REG,so that the number of the channel to be in use and the capacity of the bus to be in use will be stored in the register for channels in use REG,and the bus capacity register REG,This enables bus management to be achieved easily in a system performing synchronous communication between plural nodes connected to the bus.
