PRODUCTION DATA
| BIT | FIELD | TYPE | DEFAULT | DESCRIPTION |
|---|---|---|---|---|
| 7 | Reserved | R/W | 0 | Reserved |
| 6 | FWD_SYNC_AS_AVAIL | R/W | 0 | Synchronized Forwarding As Available During Synchronized Forwarding, each forwarding engine will wait for video data to be available from each enabled port, prior to sending the video line. Setting this bit to a 1 will allow sending the next video line as it becomes available. For example if RX Ports 0 and 1 are being forwarded, port 0 video line is forwarded when it becomes available, rather than waiting until both ports 0 and ports 1 have video data available. This operation may reduce the likelihood of buffer overflow errors in some conditions. This bit will have no affect in video line concatenation mode and only affects video lines (long packets) rather than synchronization packets. This bit applies to both CSI-2 output ports |
| 5:4 | Reserved | R/W | 0x0 | Reserved |
| 3:2 | CSI0_SYNC_FWD | R/W | 0x0 | Enable synchronized forwarding for CSI-2 output port 0 (see Section 7.4.25.2) 00: Synchronized forwarding disabled 01: Basic Synchronized forwarding enabled 10: Synchronous forwarding with line interleaving 11: Synchronous forwarding with line concatenation Only one of CSI0_RR_FWD and CSI0_SYNC_FWD must be enabled at a time. |
| 1 | Reserved | R/W | 1 | Reserved |
| 0 | CSI0_RR_FWD | R/W | 1 | Enable best-effort forwarding for CSI-2 output port 0. When this mode is enabled, no attempt is made to synchronize the video traffic. When multiple sources have data available to forward, the data will tend to be forwarded in a round-robin fashion. 0: Round robin forwarding disabled 1: Round robin forwarding enabled Only one of CSI0_RR_FWD and CSI0_SYNC_FWD must be enabled at a time. |
