Interfacing to microprocessors with bi-directional reset pins
Microprocessors with bi-directional reset pins can contend with the STM70x reset output.
For example, if the reset output is driven high and the micro wants to pull it low, signal
contention will result. To prevent this from occurring, connect a 4.7k resistor between the
reset output and the micro's reset I/O as in
Figure 11. Interfacing to microprocessors with bi-directional reset I/O
