4.32 Asynchronous Request Filter High Register

The asynchronous request filter high set/clear register enables 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 to 1 in this register, 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 device. Nonlocal bus-sourced packets are not acknowledged unless bit 31 in this register is

set to 1. See Table 4−24 for a complete description of the register contents.

4.33 Asynchronous Request Filter Low Register

The asynchronous request filter low set/clear register enables asynchronous receive requests on a per-node basis

and handles the lower node IDs. Other than filtering different node IDs, this register behaves identically to the

asynchronous request filter high register. See Table 4−25 for a complete description of the register contents.
