The value is set by user for poison base address, determined by PL Address Mapping. The XMPU replaces the incoming AXI address (39 down to 8) with the PL_SINK_ADDR. Address (7 down to 0) is retained from the originating address for alignment. Downstream, the XMPU_PL_Sink unit responds to the transaction.
