Crystal oscillator pin, Low voltage input, load capacitors external, ADC
input
LIN 2.x transceiver BUS pin, slave only, High voltage I/O
Test inputs for Melexis, debug interface - connect via resistor to GND
in application mode, so that Flashing via these test pins is possible
Test output for Melexis, debug interface, unconnected in application
mode
not connected pins
