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: 4.7k for RESET,
10k for I/Os). For the same reason, unused I/O pins must not be directly tied to V

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.
