12.11. Port Mappings
| Command Port | Allowed Functions | 
|---|---|
| 0, 2, 4 | FPGA fabric AXI read command ports FPGA fabric Avalon-MM read or write command ports | 
| 1, 3, 5 | FPGA fabric AXI write command ports FPGA fabric Avalon-MM read or write command ports | 
| 6 | L3 AXI read command port | 
| 7 | MPU AXI read command port | 
| 8 | L3 AXI write command port | 
| 9 | MPU AXI write command port | 
| Read Port | Allowed Functions | 
|---|---|
| 0, 1, 2, 3 | 64-bit read data from the FPGA fabric. When 128-bit data read ports are created, then read data ports 0 and1 get paired as well as 2 and 3. | 
| 4 | 32-bit L3 read data port | 
| 5 | 64-bit MPU read data port | 
| Write Port | Allowed Functions | 
|---|---|
| 0, 1, 2, 3 | 64-bit write data from the FPGA fabric. When 128-bit data write ports are created, then write data ports 0 and 1 get paired as well as 2 and 3. | 
| 4 | 32-bit L3 write data port | 
| 5 | 64-bit MPU write data port |
