| 14 | The Image Sensor Controller (ISC) device provides the video input capabilities for the |
| 15 | Atmel/Microchip AT91 SAMA family of devices. |
| 16 | |
| 17 | The ISC has a single parallel input that supports RAW Bayer, RGB or YUV video, |
| 18 | with both external synchronization and BT.656 synchronization for the latter. |
