Bus Arbitration Interrupt
The 7480/7481 group is provided with a built-in bus arbitration in-
terrupt as a function for bus conflict system communication.
At such bus conflict system communication, as shown in Figure
33, if transmit data cannot be transmitted to the LAN data bus due
to a transmit data collision, the data collision can be detected by
the bus arbitration interrupt.
