1. Typical values are measured at 25 °C. Characterized, not tested.
2. Only PTB4, PTB5, PTD0, PTD1, PTE0, PTE1, PTH0, and PTH1 support ultra high current output.
3. All functional non-supply pins, except for PTA2 and PTA3, are internally clamped to VSS and VDD
.
4. 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 value.
5. 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).
