2.VDDL and VKAM are adjustable to support current microprocessor technology (1.25 V to 3.3 V) by means of an external resistor divider.
3. When the 33394 CAN transceiver is not used, CANL and CANH pins can be shorted together.
4. Dp1 = reverse battery protection diode. Dp2 = load dump protection diode. Dp1, Dp2 can be ommitted in those applications which do not require such protection.
