LIN
The AT90CAN128 may support a software LIN implementation. This software LIN
implementation uses either the UART1 or a bit manipulation method on PD.2/PD.3 for
LIN master or LIN slave.
The DVK90CAN1 is ready to implement (option) an ATMEL LIN transceiver (ATA6661).
A 3-pin male connector assumes the LIN bus connections.
Note:
Figure 3-21 . LIN 3-pin Connector
The LIN 3-pin connector must provide the V-Battery (BAT) up to +12 volts and GND.
Figure 3-22 . LIN 3-pin Connections
For slave LIN, LIN Wake-up is provided by a switch (active low signal).

Due to ATA6661 design, it is mandated to enable the internal pull-up on PD.2 (RxLIN)
when LIN is used (c.f. AT90CAN128 Datasheet, section “I/O Ports”).
