18.3.30 Receive/Relay Function Set Register (Port 1 to 0) (TSU_FWSL1)
TSU_FWSL1 sets the processing method of each frame in port 1 reception and port 1 to 0 relay
operations. In receiving a frame, the processing method can be determined by referring to the
CAM evaluation results when the multicast frame and the destination are other than this LSI. (For
details, refer to section 18.4.4, CAM Function.) Writing to this register is prohibited, after relay
operations have been enabled once (after the FWEN0 in TSU_FWEN0 or the FWEN1 in
TSU_FWEN1 is set to 1).
