Interfacing to Microprocessors with Bi-
directional Reset Pins
Microprocessors with bi-directional reset pins can
contend with the STM70x reset output. For exam-
ple, 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 resis-
tor between the reset output and the micro’s reset
I/O as in Figure 12.
