DIVLSB[7:0]: LIN Baud Rate Divider Least Significant Bits.
The 8 least significant bits for the baud rate divider. The 9th and most significant bit is the
DIV9 bit (LIN0MUL.0). The valid range for the divider is 200 to 511.
ENHCHK: Checksum Selection Bit.
0: Use the classic, specification 1.3 compliant checksum. Checksum covers the data bytes.
1: Use the enhanced, specification 2.1 compliant checksum. Checksum covers data bytes
and protected identifier.
UNUSED. Read = 000b. Write = don’t care.
LINSIZE3–0: Data Field Size.
0000: 0 data bytes
0001: 1 data byte
0010: 2 data bytes
0011: 3 data bytes
0100: 4 data bytes
0101: 5 data bytes
0110: 6 data bytes
0111: 7 data bytes
1000: 8 data bytes
1001-1110: RESERVED
1111: Use the ID[1:0] bits (LIN0ID[5:4]) to determine the data length.
