Return to Summary Table.
|7-1||REMOTE_ID||R/W||0x0|| 7-bit Serializer Device ID
Configures the I2C Slave ID of the remote Serializer. A value of 0 in this field disables I2C access to the remote Serializer. This field is automatically loaded from the Serializer once RX Lock has been detected. Software may overwrite this value, but should also assert the FREEZE DEVICE ID bit to prevent loading by the Bidirectional Control Channel.
|0||FREEZE_DEVICE_ID||R/W||0x0|| Freeze Serializer Device ID
Prevent auto-loading of the Serializer Device ID from the Forward Channel. The ID will be frozen at the value written.
