Caution
Exposure to Absolute Maximum Ratings for extended periods may affect device reliability; exceeding
the ratings could cause permanent damage. The parameters apply independently. The device should
be operated within the limits specified under DC and AC Characteristics.
Remark
Unless otherwise specified, dual-function pin characteristics are the same as port pin characteristics.
