• Bits 7:6 – LP[1:0]: Parity
In LIN mode:
LP0 = LID4 ^ LID2 ^ LID1 ^ LID0
LP1 = ! ( LID1 ^ LID3 ^ LID4 ^ LID5 )
In UART mode this field is unused.
• Bits 5:4 – LDL[1:0]: LIN 1.3 Data Length
In LIN 1.3 mode:
– 00 = 2-byte response,
– 01 = 2-byte response,
– 10 = 4-byte response,
– 11 = 8-byte response.
In UART mode this field is unused.
• Bits 3:0 – LID[3:0]: LIN 1.3 Identifier
In LIN 1.3 mode: 4-bit identifier.
In UART mode this field is unused.
• Bits 5:0 – LID[5:0]: LIN 2.1 Identifier
In LIN 2.1 mode: 6-bit identifier (no length transported).
In UART mode this field is unused.

• Bits 7:4 – Reserved Bits
These bits are reserved for future use. For compatibility with future devices, they must be
written to zero when LINSEL is written.
