CHAPTER 5: Peripheral Operation

5.6.1MY TALK ADDRESS (MTA)

When the interface converter is addressed to talk, it retrieves data from the serial input buffer and outputs it to the IEEE 488 bus. It substitutes the selected IEEE bus terminators for the received serial terminators. The inter- face converter will continue to output serial input buffer data as long as the IEEE controller allows.

5.6.2MY LISTEN ADDRESS (MLA)

When the interface converter is addressed to listen, it accepts data from the active talker and outputs this data through the serial interface. It substitutes the selected serial terminators for the received IEEE bus terminators.

5.6.3DEVICE CLEAR (DCL AND SDC)

Device Clear resets the interface converter’s IEEE input and serial input buffers. Any pending data and Service Requests (SRQ), including the information they convey, are lost.

5.6.4INTERFACE CLEAR (IFC)

IFC places the interface converter in the Talker/Listener Idle State. It clears any pending requests for service (SRQ). The condition which caused the SRQ remains unmodified.

5.6.5SERIAL POLL ENABLE (SPE)

When Serial-Poll-Enabled, the interface converter sets itself to respond to a serial poll with its serial-poll status byte if addressed to talk. When the serial- poll byte is accepted by the controller, any pending SRQs are cleared. The interface converter will continue to try to output its serial-poll response until it is “Serial-Poll-Disabled” by the controller.

5.6.6SERIAL POLL DISABLE (SPD)

Disables the interface converter from responding to serial polls by the controller.

5.6.7UNLISTEN (UNL)

UNL places the interface converter in the Listener Idle State.

5.6.8 UNTALK (UNT)

UNT places the interface converter in the Talker Idle State.
