Register
Standard Event Status Register
The standard event-status register (ESR) is set if errors occur
in communication. Different causes of error set different bits,
so that errors can be specified precisely.
Standard Event Status Enable Register
An error bit is set in the standard event status register. This
only leads to the setting of the event summary bit (ESB) in the
status byte register if the associated bit is set in the standard
event status enable register (see also *ESR? command).
With this it can be established which error causes lead to the
generation of a service request.
Status Byte Register
The status Byte register contains information on whether there
is a message in the output buffer, an error has occurred or a
service request has been made. In the case of a serial poll via
the IEEE interface, the status byte register of the addressed
device is also output.
Service Request Enable Register
If a service request enable register bit and the associated bit of
the status byte register are set, this has the following effects:
* The master summary status byte (MSS) of the status
byte register (STB) is set.
* A service request is carried out.
