LINSEL – LIN Data Buffer Selection Register
LINDAT – LIN Data Register
• Bits 7:4 - Res: Reserved
• Bit 3 - LAINC: Auto Increment of Data Buffer Index
• Bits 2:0 - LINDX 2:0: FIFO LIN Data Buffer Index
• Bits 7:0 - LDATA[7:0]: LIN Data In / Data out

written to zero when LINSEL is written.
FIFO data buffer is accessed through LINDAT.
– 0 = Auto incrementation of FIFO data buffer index (default)
– 1 = No auto incrementation
– In Write access, data out
– In Read access, data in
These bits are reserved for future use. For compatibility with future devices, they must be
In LIN mode:
In UART mode this field is unused.
In LIN mode: location (index) of the LIN response data byte into the FIFO data buffer. The
In UART mode this field is unused.
In LIN mode: FIFO data buffer port.
In UART mode: data register (no data buffer - no FIFO).
