Request
(SRQ)
The 4349B can send an SRQ (Service Request) control signal when it requires the controller
to
perform a task. When the 4349B generates an SRQ, it also sets Bit 6 of the status byte
,
RQS (Request
Service) bit. Service Request Enable Register allows an application programmer
to select
which summary messages in the status byte register may cause service requests
.
