The Filter n Byte Mask registers of the Remote Wake-Up register define the bytes of the frame that are examined by filter n (0, 1, 2, and 3) in order to determine whether or not a frame is a remote wake-up frame. The most significant bit (bit 31) of each mask must be zero. Bits [30:0] are the Byte Mask. If bit j of the Byte Mask is set, then the CRC block processes the Filter n Offset + j of the incoming frame; otherwise Filter n Offset + j is ignored.
