Output Queue

Output Queue

The Output Queue stores response messages until they are read. If an unread message exists, Bit4 (Message Available − MAV) of the Status Byte Register is set to 1. So, Bit4 is used to synchronize information exchange with the controller. See Figure 5-5.

Figure 5-5 Output Queue of B2200

The Response Formatter places Data Byte Messages and END messages into the Output Queue in response to query commands. These messages are removed from the Output Queue as they are read by the controller. As long as the Output Queue contains an unread message, MAV is 1.
