Caution If the rated value of even one of the above parameters is exceeded even momentarily, the quality
of the product may be degraded. The absolute maximum ratings, therefore, are the values
exceeding which the product may be physically damaged. Be sure to use the product with these
ratings never being exceeded.
Remark
Unless otherwise specified, the characteristics of a multiplexed pin are the same as those of the
corresponding port pin.
