ATmega32/64/M1/C1

17.6.9 LIN Data Buffer Selection Register - LINSEL

• 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.

• 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.

17.6.10 LIN Data Register - LINDAT

• 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.
