Interfacing to microprocessors with bidirectional reset pins

Microprocessors with bidirectional reset pins can contend with the STM705-708 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 4.7 k resistor

between the reset output and the micro's reset I/O as in Figure 11.
