This parameter is characterized and not tested on each device.

Measurement condition for pull resistors: V
In
= V
SS
for pullup and V
In
= V
DD
for pulldown.
4
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.
5
All functional non-supply pins are internally clamped to V
SS
and V
DD
.
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.
7
This parameter is characterized and not tested on each device.
8
IRQ does not have a clamp diode to V
DD
. Do not drive IRQ above V
DD
.
