The POISON register is shown in the following table.
| Field Name | Bits | Type | Reset Value | Description |
|---|---|---|---|---|
| PL_SINK_ADDR | 31:0 | rw | 0x00800000 |
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. |
