Rev 1.0
Turn signal mapped to PA8 but that is not an ADC Pin
Resolution: Rev 1.1
Rev 1.1
Remapped stalk input from PA8 to PA5

Transient voltage suppressor (TVS) diodes (or Zener diodes)
Unidirectional - good if the polarity of an ESD event is known with respect to the system I/O
Bidirectional - good if the polarity of an ESD event is unknown with respect to the system I/O
Weakness: Transient oscillations can cause TVS diodes to fail
ESD suppressors
generally use TVS diodes
