• Bits 7:4 - Res: Reserved

These bits are reserved for future use. For compatibility with future devices, they must be

written to zero when LINSEL is written.

• Bit 3 - LAINC

: Auto Increment of Data Buffer Index

In LIN mode:

– 0 = Auto incrementation of FIFO data buffer index (default),

– 1 = No auto incrementation.

In UART mode this field is unused.

• Bits 2:0 - LINDX 2:0: FIFO LIN Data Buffer Index

In LIN mode: location (index) of the LIN response data byte into the FIFO data buffer. The

FIFO data buffer is accessed through LINDAT.

In UART mode this field is unused.

21.6.10 LINDAT – LIN Data Register

• Bits 7:0 - LDATA[7:0]: LIN Data In / Data out

In LIN mode: FIFO data buffer port.

In UART mode: data register (no data buffer - no FIFO).

– In Write access, data out.

– In Read access, data in.
