PRODUCTION DATA
CSI-2 TX port-specific register. The CSI-2 Port Select register 0x32 configures which unique CSI-2 TX port registers can be accessed by I2C read and write commands.
| BIT | FIELD | TYPE | DEFAULT | DESCRIPTION |
|---|---|---|---|---|
| 7:5 | RESERVED | - | 0x0 | Reserved |
| 4 | TX_PORT_NUM | R | 0 | TX Port Number This read-only field indicates the number of the currently selected TX read port. |
| 3:2 | RESERVED | - | 0x0 | Reserved |
| 1 | TX_PORT_SYNC | R | 0 | TX Port Synchronized This bit indicates the CSI-2 Transmit Port is able to properly synchronize input data streams from multiple sources. This bit is 0 if synchronization is disabled via the FWD_CTL2 register. 0 : Input streams are not synchronized 1 : Input streams are synchronized |
| 0 | TX_PORT_PASS | R | 0 | TX Port Pass Indicates valid data is available on at least one port, or on all ports if configured for all port status via the CSI_PASS_MODE bit in the CSI_CTL2 register. The function differs based on mode of operation. In asynchronous operation, the TX_PORT_PASS indicates the CSI-2 port is actively delivering valid video data. The status is cleared based on detection of an error condition that interrupts transmission. During Synchronized forwarding, the TX_PORT_PASS indicates valid data is available for delivery on the CSI-2 TX output. Data may not be delivered if ports are not synchronized. The TX_PORT_SYNC status is a better indicator that valid data is being delivered to the CSI-2 transmit port. |
