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.

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.

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).
