4.35 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
handles 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. See Table 4–26 for a complete description of
the register contents.

Table 4–26. Physical Request Filter Low Register Description
BIT FIELD NAME TYPE DESCRIPTION
31 physReqResource31 RSC
If this bit is set for local bus node number 31, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
30 physReqResource30 RSC
If this bit is set for local bus node number 30, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
Bits 29 through 2 follow the same pattern.
1 physReqResource1 RSC
If this bit is set for local bus node number 1, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
0 physReqResource0 RSC
If this bit is set for local bus node number 0, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
