4.38 Physical Request Filter Low Register
The physical request filter low set/clear register enables 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 to 1 in this register, then the request is handled by the asynchronous request
context instead of the physical request context. See Table 431 for a complete description of the register contents.

DESCRIPTION
31
physReqResource31
RSC
If bit 31 is set to 1 for local bus node number 31, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
30
physReqResource30
RSC
If bit 30 is set to 1 for local bus node number 30, physical requests received by the TSB82AA2
device from that node are handled through the physical request context.
292
physReqResourcen
RSC
Bits 29 through 2 (physReqResourcen, where n = 29, 28, 27,
…
, 2) follow the same pattern as
bits 31 and 30.
1
physReqResource1
RSC
If bit 1 is set to 1 for local bus node number 1, physical requests received by the TSB82AA2 device
from that node are handled through the physical request context.
0
physReqResource0
RSC
If bit 0 is set to 1 for local bus node number 0, physical requests received by the TSB82AA2 device
from that node are handled through the physical request context.
4.39 Physical Upper Bound Register (Optional Register)
The physical upper bound register is an optional register and is not implemented. This register returns all 0s when
read.
