|
| 10 | 1 | ||
| 11 | 1 | * PCI Express 1.1 x1,x4,x8 or 2.0 x4 |
|
| 12 | 1 | * two address space: BAR0, BAR1 |
|
| 13 | 1 | * access to registers can only be single 32-bit instructions |
|
| 14 | 1 | * local bus: 64 bit, 266 MHz |
|
| 15 | 1 | * two independent bidirectional DMA channel |
|
| 16 | 1 | * DMA channel only works in the SCATTER-GATHER mode |
|
| 17 | 1 | * The minimum unit of data for channel DMA - 4 kB |
|
| 18 | 1 | * Descriptors combined into the block descriptors. The maximum number of descriptors in the block - 63 |
|
| 19 | 1 | * DMA channel uses 40 bit addresses |
