... 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 100 kΩ resistor is recommended. Note: The same situation applies for the active-high RST of the STM810/812. A 100 k resistor to V should be used if RST must remain valid for V CC ...
