PRODUCTION DATA
The status of the CSI-2 Transmitter can be monitored by readback of the CSI_STS register 0x35, or brought to one of the configurable GPIO pins as an output. The TX_PORT_PASS 0x35[0] indicates valid CSI-2 data being presented on CSI-2 port. If no data is being forwarded or if error conditions have been detected on the video data, the CSI-2 Pass signal is cleared. The TX_PORT_SYNC 0x35[0] indicates the CSI-2 Tx port is able to properly synchronize input data streams from multiple sources. TX_PORT_SYNC always returns 0 if Synchronized Forwarding is disabled. Interrupts can also be generated based on changes in the CSI-2 port status.
