Caution Product quality may suffer if the absolute maximum rating is exceeded for even a single parameter,
or even momentarily. In other words, 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
Unless specified otherwise, dual-function pin characteristics are the same as port pin characteristics.
Notes 1.
The rms should be calculated as follows: [rms value] = [Peak value]
