Interfacing to μPs with
Bidirectional Reset Pins
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 4.7k ? resistor between the MAX709
RESET output and the μP reset I/O (see Figure 3).
Buffer the MAX709 RESET output to other system com-
ponents.
