circuit. In most systems this is not a problem, as most MCUs do not operate below 1V.
However, in applications where RST output must be valid down to 0V, a pull-down resistor
may be added to hold the RST output low. This resistor must be large enough to not load
the RST output, and still be small enough to pull the output to Ground. A 100KΩ resistor is
recommended.
