SR[7:0]. Each demultiplexer output selected by its Node Pointer = x (x = 0-7) is
connected to one input of the SRx OR-Gate. This wiring scheme also supports the
connection of more than one event source to an service request output SRx. One
receiver event, the interrupt Command Frame event, has a special characteristic: its
node pointer is controlled by the received CMD value directly and only SR[3:0] OR-Gates
are selectable.
Figure 23-38 shows the service request compressing logic. For reasons of simplicity,
not all MLI events, connections, and OR-Gates are explicitly shown. The OR-Gate inputs
are connected to the demultiplexers of the MLI event specific lines. Furthermore, a
service request output SRx can be triggered by software if the corresponding interrupt
set bit in register GINTR is written with a 1.
