ADVANCE INFORMATION
The DLC (Data Length Code) of the received frame must match exactly the configured DLC if the data mask bit is set. The DLC is configured in 8'h38[4:1]. The data mask bit is set in 8'h38[0]. While the FD DLC are included in this table, it is important to note that selective wake only works for classic CAN frames, so CAN FD codes aren't used in WUF validation.
