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 VDD range during instantaneous and operating maximum current conditions. If}
positive injection current (V_In > V_DD) is greater than I_DD, the injection current may flow out of V_DD and could result in external power supply
going out of regulation. Ensure external V_DD 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.
