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
