Device- or Counter-Specific Error
An <error number> in the range [−300 to −399] or [+1 to +32767] indicates
that the Counter has detected an error that is not a command error,
a query error, or an execution error; some Counter operations did not
properly complete, possibly due to an abnormal hardware or firmware
condition. These codes are also used for self-test response errors.
The occurrence of any error in this class causes the device-specific error
bit (bit 3) in the Event Status Register to be set.
Query Error
An <error number> in the range [−400 to −499] indicates that the output
queue control of the Counter has detected a problem with the message
exchange protocol. The occurrence of any error in this class causes the
query-error bit (bit 2) in the Event Status Register to be set. This means
that one of the following conditions exists:
• An attempt is being made to read data from the output queue when no
output is either present or pending.
• Data in the output queue was lost.
