Two register controls allow control of CSI-2 Transmitter outputs to disable the CSI-2 Transmitter outputs. If the OUTPUT_SLEEP_STATE_SELECT (OSS_SEL) control is set to 0 in the GENERAL_CFG 0x02 register (Table 23), the CSI-2 Transmitter outputs are forced to the HS-0 state. If the OUTPUT_ENABLE (OEN) register bit is set to 0 in the GENERAL_CFG register, the CSI-2 pins are set to the high-impedance state.
For normal operation (OSS_SEL and OEN both set to 1), the detection of activity on FPD3 inputs determines the state of the CSI-2 outputs. The FPD3 inputs are considered active if the Receiver indicates valid lock to the incoming signal. For a CSI-2 TX port, lock is considered valid if any Received port mapped to the TX port is indicating Lock.
