1 Typical values are measured at 25
C. Characterized, not tested
2 DC potential difference.
3 When keyboard interrupt is configured to detect rising edges, pulldown resistors are used in place of pullup resistors.
4 The specified resistor value is the actual value internal to the device. The pullup value may measure higher when measured externally
on the pin.
5 Power supply must maintain regulation within operating V
DD 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 consuming power. Examples are: if no system clock is present, or if clock rate is very low (which would reduce
overall power consumption).
6 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.
