input voltage, as well as shorting either pin to ground or ADDR-L pin to battery
voltage. However, depending on battery voltage and ID-tag value, shorting ADDR-H
to battery voltage may generate an input voltage in acceptable range and thus an
erratic ID value which cannot be detected.
Reference voltage shall be only +8V for ID-Tag usage.
