Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on
the verge of suffering physical damage, and therefore the product must be used under conditions
that ensure that the absolute maximum ratings are not exceeded.
Remarks 1.
Unless specified otherwise, the characteristics of alternate-function pins are the same as those of
port pins.
2.
Refer to
14.7 Calculation of Total Power Dissipation
for details of how to calculate the total power
dissipation.
