Pin input voltage
The input voltage measurement on a pin of the device is described in
Figure 7.
Absolute maximum ratings
Stresses above those listed as “absolute maximum ratings” may cause permanent damage
to the device. This is a stress rating only and functional operation of the device under these
conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.

or pull-down resistor (typical: 4.7kΩ for RESET, 10kΩ for I/Os).
