External crystal
Necessary for the CAN network precision, the following crystal frequency allows proper
ATAVRAUTO100 operations
(1)
: 8MHz, 12MHz, 16MHz. The ATAVRAUTO100 comes
with a default 8MHz crystal oscillator (CAN baut rate up to 1MBit/sec).
The LIN master mode clock should always be a crystal or external clock oscillator. Cur-
rently, only 8MHz and 16MHz crystal oscillator is supported.
Figure 2-3. Crystal Oscillator connection.
Note:
Only the 8MHz and 16MHz frequency are supported by the CAN and LIN libraries

LIN
Connection to the LIN network is made via the LIN connector JP3. The LIN signal must
be connected to the pin 2 of the connector.
