Pin input voltage
The input voltage measurement on a pin of the device is described in
Figure 63. Pin input voltage
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.

internal reset is generated or an unexpected change of the I/O configuration occurs (for example, due to a
corrupted program counter). To guarantee safe operation, this connection has to be done through a pull-up
or pull-down resistor (typical: 4.7 kΩ for RESET, 10 kΩ for I/Os). For the same reason, unused I/O pins
must not be directly tied to V

pads, there is no positive injection current, and the corresponding V
