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
All functional non-supply pins are internally clamped to V
SS
and V
DD
.
7
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.
