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.
|4||TX_PORT_NUM||R||0||TX Port Number
This read-only field indicates the number of the currently selected TX read port.
|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.
