When CSI-2 Transmitter is enabled in CSI_CTL register bit 0x33[0], by default the output will transition to LP11 state. Once enabled, it is typically best to leave the CSI-2 Transmitter enable, and only change the forwarding controls if changes are required to the system. When enabling and disabling the CSI-2 Transmitter, forwarding should be disabled to ensure proper start and stop of the CSI Transmitter.

When enabling and disabling the CSI-2 Transmitter, use the following sequence:

To Disable:

1. Disable forwarding for assigned ports in the FWD_CTL1 register.
2. Disable CSI periodic calibration (if enabled) in the CSI_ CTL2 register.
3. Disable continuous clock operation (if enabled) in the CSI_ CTL register.
4. Clear CSI Transmit enable in CSI_ CTL register.

To Enable:

1. Set CSI Transmit enable (and continuous clock if desired) in CSI_ CTL register.
2. Enable CSI periodic calibration (if desired) in the CSI_CTL2 register.
3. Enable forwarding for assigned ports in the FWD_CTL1 register.
