Non-Volatile Configuration 5-7
A24 Assign Base
This entry determines the A24 address where the Resource
Manager will begin allocating A24 address space for VXI devices.
This field can be used to avoid conflicts with VME devices using
A24 address space. A bus master can access the range of
address space a particular device is configured to occupy. The
VXIbus specification requires A24 bus masters to see addresses
from 200000h to DFFFFFh.
A32 Assign Base
This entry determines the A32 address where the Resource
Manager will begin allocating A32 address space for VXI devices.
This field is used to avoid conflicts with VME devices using A32
address space. A bus master can access the range of address
space that a particular device is configured to occupy. The
VXIbus specification requires A32 bus masters to see addresses
from 20000000h to DFFFFFFFh.
DC Starting Logical
Address
This parameter specifies the first logical address the Resource
Manager uses to begin assigning Dynamic Configuration (DC)
devices. DC devices will be assigned the next higher unassigned
logical address.
BNO
This parameter specifies whether the Resource Manager should
send Identify Commander and Begin Normal Operation in a DC
system. DC systems cannot specify an intended hierarchy, and
must be configured externally (normally through the local
commands
DCGrantDev
and
DCBNOsend
). The most common
configuration is to assign all DC devices to Logical Address 0 (the
RM). If BNO is specified to be sent, all DC devices are assigned
to Logical Address 0, and the Identify Commander and Begin
Normal Operation commands are sent. If BNO is specified not to
be sent, no devices (either SC or DC) will be sent the Begin
Normal Operation command.
DCBNOsend
must be sent to the
local command set to initiate normal operation after the hierarchy
is established.
For FAILED Device
The VXIbus specification requires Commanders to Sysfail-Inhibit a
Servant device that has failed (asserted the SYSFAIL* line and the
Passed bit in its Status register). The specification permits
Commanders to also set the reset bit of a failed device. This
parameter specifies which method to use.
