Note
When the system IRQ line is disabled, the remote controller functionality is not
available. Enable the system IRQ line if you are using a multi-mainframe system.
The VXI IRQ designated as system IRQ line cannot be disabled using the
DisableVXIint()
or
DisableVXItoSignalInt()
functions. The VXIpc controller
always acknowledges it automatically when it is the Resource Manager.
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
VXIpc controller 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 VXIpc
controller’s 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 VXIpc is configured as a message-based device.
Note
If the VXIpc controller is the Resource Manager (Logical Address 0), this setting is
irrelevant.
Number of Handlers
This field gives the number of interrupt handlers that the VXIpc controller
supports.
Number of Interrupters
This field gives the number of interrupters that the VXIpc controller
supports.
