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.
Remark
Unless specified otherwise, the characteristics of alternate-function pins are the same as those of port
pins.
Notes 1.
The rms value should be calculated as follows: [rms value] = [Peak value]
