Caution The following electrical specifications are preliminary values for this product. When designing,
be sure to refer to the data sheet describing the official electrical specifications.

Note
r.m.s. (root mean square) value should be calculated as follows: [r.m.s value] = [Peak value]
×
√
duty
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 an alternate-function pin and a port pin are the same unless specified otherwise.
