3.1 Definition: Operating requirement
Terminology and guidelines
An operating requirement is a specified value or range of values for a technical
characteristic that you must guarantee during operation to avoid incorrect operation and
possibly decreasing the useful life of the chip.
3.1.1 Example
This is an example of an operating requirement, which you must meet for the
accompanying operating behaviors to be guaranteed:

3.2 Definition: Operating behavior
An operating behavior is a specified value or range of values for a technical
characteristic that are guaranteed during operation if you meet the operating requirements
and any other specified conditions.
3.2.1 Example
This is an example of an operating behavior, which is guaranteed if you meet the
accompanying operating requirements:

3.3 Definition: Attribute
An attribute is a specified value or range of values for a technical characteristic that are
guaranteed, regardless of whether you meet the operating requirements.

1. All 5 V tolerant digital I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode connection
to VDD. If VIN greater than VDIO_MIN (=VSS-0.3V) is observed, then there is no need to provide current limiting resistors at
the pads. If this limit cannot be observed then a current limiting resistor is required. The negative DC injection current
limiting resistor is calculated as R=(VDIO_MIN-VIN)/|IIC|.
2. Analog pins are defined as pins that do not have an associated general purpose I/O port function.
