The DS90UB662-Q1 provides a mechanism to broadcast I2C writes to remote devices (either remote slaves or serializers). For each Receive port, the SlaveID/Alias register pairs would be programmed with the same SlaveAlias value so they would each respond to the local I2C access. The SlaveID value would match the intended remote device address, either remote slave or serializers. For each receive port, on of the SlaveAlias registers is set with an Alias value. For each port, the SlaveID value is set to the address of the remote device. These values may be the same. To access the remote serializer registers rather than a remote slave, the serializer ID (SER_IDx or SER_IDy) would be used as the SlaveID value.
