not finished reading a response (from the Output Queue) and is already sending new data. Lastly, Query Error is reported when there is a Deadlock situation: Output Queue and Input Queue are both full. This situation is unlikely to happen due to the Input Queue being able to hold several Commands and Queries.

The Register has the same structure as the Standard Event Status Register.
Performing a bit by bit AND between the Event Register and the Event Enable Register and then ORing the resulting bits, generate the Status Summary Message ESB (Event Summary Bit).
Setting new value to the Register causes a

The Primary Event Status Register has the same structure as the Primary Status Register. The bits in the Event Register are “sticky” - once a bit is set it will remain set even if the condition that caused it to be set is no longer valid.
The register is cleared when read and <rqs> and <ist> are

The Primary Event Status Enable Register has the same structure as the Primary Status Register.
The Status Summary Message PRIM_ERR is calculated by performing a bit by bit AND between the Primary Event Status Register and the Primary Event Status Enable Register and then ORing the resulting bits.
