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.

unintentional 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 k
