The subsystem can calculate and add the FCS field to each transmitted frame, or it can pass through a user-supplied FCS field with frame data. When a user-supplied FCS field is passed through, you must also supply padding as necessary to ensure that the frame meets the minimum frame length requirement. FCS insertion or pass through is controlled by the TEMAC Transmit Control (TC) register bit 29 (Table 2).
