Bit7:
ENHCHK: Checksum version selection bit
1 - Spec. 2.0, inverted eight bit sum with carry over all data bytes and protected identifier.
0 - Spec 1.3, inverted eight bit sum with carry over all data bytes.
Bit6–4: UNUSED. Read = 00b. Write = don’t care.
Bit3–0: LINSIZE3–0: LIN data field size.
If the LINSIZE bits are filled (“1111b’) then the size of the data field is defined as a function of
the two most significative bits of the identifier as defined in the table below, otherwise is
defined by the LINSIZE3–0 bits.
