2
When a pin interrupt is configured to detect rising edges, pulldown resistors are used in place of pullup resistors.

Maximum is highest voltage that POR is guaranteed.

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).
if clock rate is very low which (would reduce overall power consumption).

All functional non-supply pins are internally clamped to V
SS
and V
