| 2 | |
| 3 | The GRUSBDC USB Device Controller core is available in the GRLIB VHDL |
| 4 | IP core library. |
| 5 | |
| 6 | Note: In the ordinary environment for the core, a Leon SPARC system, |
| 7 | these properties are built from information in the AMBA plug&play. |
| 8 | |
| 9 | Required properties: |
| 10 | |
| 11 | - name : Should be "GAISLER_USBDC" or "01_021" |
| 12 | |
| 13 | - reg : Address and length of the register set for the device |
| 14 | |
Andreas Larsson | d9a6ef1 | 2014-03-27 16:15:54 +0100 | [diff] [blame] | 15 | - interrupts : Interrupt numbers for this device. Either one interrupt number |
| 16 | for all interrupts, or one for status related interrupts, one for IN |
| 17 | endpoint related interrupts and one for OUT endpoint related interrupts. |

| 19 | Optional properties: |
| 20 | |
Andreas Larsson | d9a6ef1 | 2014-03-27 16:15:54 +0100 | [diff] [blame] | 21 | - epobufsizes : Array of buffer sizes for OUT endpoints when they differ |
| 22 | from the default size of 1024. The array is indexed by the OUT endpoint |
| 23 | number. If the property is present it typically contains one entry for |
| 24 | each OUT endpoint of the core. Fewer entries overrides the default sizes |
| 25 | only for as many endpoints as the array contains. |

| 28 | from the default size of 1024. The array is indexed by the IN endpoint |
| 29 | number. If the property is present it typically contains one entry for |
| 30 | each IN endpoint of the core. Fewer entries overrides the default sizes |
| 31 | only for as many endpoints as the array contains. |
