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). Unused I/O pins must be tied in the
