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.

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.
