4.34 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
handles 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. The node ID comparison is done if the source node is on the same bus as the TSB42AD2. Nonlocal
bus sourced packets are not acknowledged unless bit 31 in this register is set. See Table 4–25 for a complete
description of the register contents.

BIT FIELD NAME TYPE DESCRIPTION
31 physReqAllBusses RSC
If this bit is set, then all physical requests received by the TSB12LV26 from non-local bus nodes
are accepted.
30 physReqResource62 RSC
If this bit is set for local bus node number 62, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
29 physReqResource61 RSC
If this bit is set for local bus node number 61, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
28 physReqResource60 RSC
If this bit is set for local bus node number 60, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
27 physReqResource59 RSC
If this bit is set for local bus node number 59, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
26 physReqResource58 RSC
If this bit is set for local bus node number 58, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
25 physReqResource57 RSC
If this bit is set for local bus node number 57, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
24 physReqResource56 RSC
If this bit is set for local bus node number 56, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
23 physReqResource55 RSC
If this bit is set for local bus node number 55, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
22 physReqResource54 RSC
If this bit is set for local bus node number 54, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
21 physReqResource53 RSC
If this bit is set for local bus node number 53, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
20 physReqResource52 RSC
If this bit is set for local bus node number 52, then physical requests received by the TSB12LV26
from that node are handled through the physical request context.
