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
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 VSS5 or VDD5).

1 Beyond absolute maximum ratings device might be damaged.
2 The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. The absolute
maximum ratings apply when the device is powered from an external source.
3 All digital I/O pins are internally clamped to VSSX1/2 and VDDX1/2 or VSSA and VDDA.
4 Ports U, V and W are internally clamped to VSSM1/2/3 and VDDM1/2/3.
5 Those pins are internally clamped to VSSPLL and VDDPLL.
6 This pin is clamped low to VSSPLL, but not clamped high. This pin must be tied low in applications.
