4.35 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, 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 TSB82AA2B device. Nonlocal bus-sourced packets are not acknowledged unless bit 31
in this register is set to 1. None of the bits in this register can be accessed while a bus reset interrupt is pending in
the interrupt event register at 80h/84h. See Table 4−28 for a complete description of the register contents.
