Internal Registers
Physical Request Filter High Register
The Physical Request Filter High set/clear register is used to enable physical receive requests on a per-node
basis and handle the upper-node IDs. When a packet is destined for the physical request context and the node ID
has been compared against the ARRQ registers, then the comparison is done again with this register. If the bit
corresponding to the node ID is not set in this register, then the request is handled by the ARRQ context instead
of the physical request context.

Table 51. Physical Request Filter High Register Description
Physical Request Filter Low Register
The Physical Request Filter Low set/clear register is used to enable physical receive requests on a per-node
basis and handle the lower-node IDs. When a packet is destined for the physical request context and the node ID
has been compared against the Asynchronous Request Filter registers, then the node ID comparison is done
again with this register. If the bit corresponding to the node ID is not set in this register, then the request is
handled by the asynchronous request context instead of the physical request context.

Type
RSC If this bit is set, requests received by the FW322 from local bus node N
(where N = bit number) will be handled through the physical request context.
Set/Clear operations to this register while the IntEvent.busReset bit (see
Table 39) is asserted will have no effect. All physReqResourceN bits will be
cleared to zero when a bus reset occurs.
from nonlocal bus nodes are accepted. Set/Clear operations to this
register while the IntEvent.busReset bit (see Table 39) is asserted will
have no effect. A bus reset will not affect the value of the physReqRe-
sourceAllBuses bit.
(where N = bit number + 32) will be handled through the physical
request context. Set/Clear operations to this register while the
IntEvent.busReset bit (see Table 39) is asserted will have no effect. All
physReqResourceN bits will be cleared to zero when a bus reset
occurs.
