Caution Product quality may suffer if the absolute maximum rating is exceeded for even a single

parameter even momentarily. 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 which ensure that the absolute maximum ratings are not exceeded.

Remark The characteristics of alternate-function pins and port pins are the same unless specified otherwise.
