2.3.2 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.
