Datasheet

Digital converter. The resulting voltage defines the physical address that the communication handler will
use when the node will participate in LIN communication.
In automotive applications, distributed voltages are very disturbed. The internal Current Source solution of
ATmega16M1/32M1/64M1 immunizes the address detection against any kind of voltage variations.
