4.3 Reset Circuitry

The 78M6610+PSU employs an active low Reset input pin. Figure 8 shows the external circuit

configuration using a pushbutton switch to generate the reset signal. If an external reset is not required,

connect the Reset pin to V

3P3

. An external reset is typically only used during the development phase of a

project. The RESET pin can be tied high for the production version of the PCB.
