Caution
Product quality may suffer if the absolute maximum rating is exceeded for even single
parameter or even momentarily. That is, the absolute maximum ratings are the rated values at
which the product is on the verge of suffering physical damage, and therefore the product must
be used under conditions which ensure that the absolute maximum ratings are not exceeded.
Remark
The characteristics of an alternate function pin and a port pin are the same unless specified otherwise.
