Electrical Characteristics
3.1
General
This supplement contains electrical information for the embedded MC9S12I32 microcontroller die, as well as the MM912F634
analog die.
3.2
Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima is not guaranteed.
Stress beyond those limits may affect the reliability or cause permanent damage of the device.
This device contains circuitry protecting against damage due to high static voltage or electrical fields. However, it is advised that
normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance
circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. All voltages are with respect
to ground unless otherwise noted.

Note:
6. Caution: As this pin is adjacent to the VDDX pin, care should be taken to avoid a short between VDD and VDDX, for example, during
the soldering process. A short-circuit between these pins might lead to permanent damage.
