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

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 (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.
