| 13 | description: | |
| 14 | The eXtended Image Sensor Controller (XISC) device provides the video input capabilities for the |
| 15 | Microchip AT91 SAM family of devices. |
| 16 | |
| 17 | The XISC has a single internal parallel input that supports RAW Bayer, RGB or YUV video. |
| 18 | The source can be either a demuxer from a CSI2 type of bus, or a simple direct bridge to a |
| 19 | parallel sensor. |
| 20 | |
| 21 | The XISC provides one clock output that is used to clock the demuxer/bridge. |

| 48 | description: |
| 49 | As the XISC is usually connected to a demux/bridge, the XISC receives |
| 50 | the same type of input, however, it should be aware of the type of |
| 51 | signals received. The mipi-mode enables different internal handling |
| 52 | of the data and clock lines. |
