1. Typical values are measured at 25 °C. Characterized, not tested.

2. The specified resistor value is the actual value internal to the device. The pullup value may appear higher when

measured externally on the pin.

3. This item applies to the GPIO share pads only.

4. All functional non-supply pins, except for PTA6 and PTA7, are internally clamped to VDD.

5. 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 large one.

6. Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum current

conditions. If the positive injection current (VIn > VDD) is higher than IDD, the injection current may flow out of VDD and

could result in external power supply going out of regulation. Ensure that external VDD load will shunt current higher than

maximum injection current when the MCU is not consuming power, such as no system clock is present, or clock rate is

very low (which would reduce overall power consumption).
