A resistor tied from the device RT pin to AGND is used to set operating frequency. Use Equation 2 or refer to Figure 8-5 for resistor values. Note that a resistor value outside of the recommended range can cause the device to shut down. This prevents unintended operation if RT pin is shorted to ground or left open. Do not apply a pulsed signal to this pin to force synchronization. If synchronization is needed, refer to Section 8.3.2.
