1. Detects intermittent Opens or Closes lasting for at least 250 μsec.

2. Test current of 0.5 mA with maximum open circuit voltage of 2.8 V is used.

4. Count only low to high transition for initial switch condition of Low.

5. Count only high to low transition for initial switch condition of High.
