4.32 Asynchronous Request Filter High Register
The asynchronous request filter high set/clear register is used to enable asynchronous receive requests on a
per-node basis, and handles the upper node IDs. When a packet is destined for either the physical request context
or the ARRQ context, the source node ID is examined. If the bit corresponding to the node ID is not set in this register,
then the packet is not acknowledged and the request is not queued. The node ID comparison is done if the source
node is on the same bus as the TSB12LV26. Nonlocal bus sourced packets are not acknowledged unless bit 31 in
this register is set. See Table 4–23 for a complete description of the register contents.

BIT FIELD NAME TYPE DESCRIPTION
31 asynReqAllBuses RSC
If this bit is set, then all asynchronous requests received by the TSB12LV26 from nonlocal bus
nodes are accepted.
30 asynReqResource62 RSC
If this bit is set for local bus node number 62, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
29 asynReqResource61 RSC
If this bit is set for local bus node number 61, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
28 asynReqResource60 RSC
If this bit is set for local bus node number 60, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
27 asynReqResource59 RSC
If this bit is set for local bus node number 59, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
26 asynReqResource58 RSC
If this bit is set for local bus node number 58, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
25 asynReqResource57 RSC
If this bit is set for local bus node number 57, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
24 asynReqResource56 RSC
If this bit is set for local bus node number 56, then asynchronous requests received by the
TSB12LV26 from that node are accepted.
