A.1.3.4
This pin is used for production testing only. The TEST pin must be tied to V
A.1.4
Power supply must maintain regulation within operating V
operating maximum current conditions. If positive injection current (V
the injection current may flow out of V
regulation. Ensure external V
will be the greatest risk when the MCU is not consuming power; e.g., if no system clock is present, or if
clock rate is very low which would reduce overall power consumption.
A.1.5
Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima
is not guaranteed. Stress beyond those limits may affect the reliability or cause permanent damage of the
device.
This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (e.g., either V
