Microprocessors with bidirectional reset pins (such as  
the Motorola 68HC11 series) can contend with the  
MAX709 reset output. If, for example the MAX709  
RESET output is asserted high and the µP wants to pull  
it low, indeterminate logic levels may result. To correct  
this, connect a 4.7kresistor between the MAX709  
RESET output and the µP reset I/O (see Figure 3).  
Buffer the MAX709 RESET output to other system com-  
ponents.
