System IRQ Level
The remote controllers—in this case the VXI/VME-MXI-2—can report
events such as triggers and DMA to the PCI-MXI-2 through a VXI IR Q
line. This field selects which VXI IRQ level the remote controllers
should use to report events to the PCI-MXI-2.
Servant Area Size
This field designates the servant area size, which is supplied to the
Resource Manager in response to the Read Servant Area command
(if the PCI-MXI-2 is not the Resource Manager in your system). The
servant area size is an 8-bit value (0 through 255) that indicates the
servant area. The servant area begins at the logical address following
the PCI-MXI-2 logical address, and includes N contiguous logical
addresses, where N is the value of the servant area size. This field is
meaningful only when the PCI-MXI-2 is configured as a message-based
device.
Note: If the PCI-MXI-2 is the Resource Manager (Logical Address 0), this setting
is irrelevant.
Number of Handlers
This field gives the number of interrupt handlers that the PCI-MXI-2
supports.
Interrupt Request Levels Default Value
1 to 7 1
Servant Area Range Default Value
0 to 255 0
Interrupt Handlers Default Value
0 to 7 1
