Service
Request
(SRQ)
The 4263B can send an SRQ (Service Request) control signal when it requires the controller
to
perform a task. When the 4263B generates an SRQ, it also sets Bits 6 of the Status Byte
Register,
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. (Illustrates
in status-byte
.)
