CC2530: Avoid unwanted Resets

Part Number: CC2530

Hi,

I have left the RST pin of the CC2530 unconnected and noticed that it was very susceptible to noise (as if it were a floating pin). Often times, when the CC2530 tells my motor driver to turn a motor, it would cause an unwanted Reset. My oscilloscope showed that the voltage dropped significantly on the RST pin, causing this reset. I have found from: https://e2e.ti.com/support/wireless_connectivity/low_power_rf_tools/f/155/t/49674 , that an RC filter can be used to fix this problem. I wanted to ask what are the recommended (resistor and capacitor) values for this RC filter?
