Status Byte/Service Request Enable Register
The Status Byte Register is an 8-bit register that summarizes the Summary
Message Bits from the status register groups and the Output Queue. The Status
Byte Register can be used to send a Service Request (SRQ) to the controller.
Service request enabling allows the application programmer to select which
Summary Messages in the Status Byte Register may cause a service request.
The Service Request Enable Register, illustrated in
figure 32
, is an 8-bit register
that enables corresponding Summary Messages in the Status Byte Register.
Table 23
details the Status Byte Register bit assignments.
