1. The device always interprets an input as a 1 when the input is greater than or equal to VIH (min.) and less than or equal to
VIH (max.), regardless of whether input hysteresis is turned on.
2. The device always interprets an input as a 0 when the input is less than or equal to VIL (max.) and greater than or equal to
VIL (min.), regardless of whether input hysteresis is turned on.
3. All functional non-supply pins are internally clamped to VSS and VDD. Input must be current limited to the value specified.
To determine the value of the required current-limiting resistor, calculate resistance values for positive and negative clamp
voltages, then use the larger of the two values. Power supply must maintain regulation within operating VDD range during
instantaneous and operating maximum current conditions. If positive injection current (VIn > VDD) is greater than IDD, the
injection current may flow out of VDD and could result in external power supply going out of regulation. Ensure external
VDD load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not
