5EOI End Or Indentify has two uses. EOI is asserted on the last byte of a data transfer. This signals all devices that no more data should be expected on the transfer.
6DAV Data Valid is a handshake line indicating that the active talker has placed data on the data lines.
7NRFDNot Ready For Data is a handshake line indicating that one or more active listeners is not ready for more data. Note the active talker should then wait before sending any more data on the bus.
8NDAC Not Data Accepted is a handshake line indocating that one or more active listeners has not accepted the current data byte. Note the active talker should leave the current byte asserted on the data lines until it has been accepted ot timed out.
9IFC Interface Clear is under the exclusive control of the system controller. When it is active high all devices on the bus are returned to an idle state and the bus is cleared
10SRQ Service Request can be set by a devive on the interface to indicate it is in need of service. SRQ could be set at the completion of a task. E.g. finished doing a measurement, or when an error as occurred.
11ATN Attention is used primarily to differentiate between command mode and data mode. When ATN is TRUE (I.E. Active high) information on the bus is a command and when ATN is FALSE (Active LOW) the information on the bus is data.
