4.5. What is the purpose of having damping resistors placed near UART terminals?
They are there to reduce the amount of radiation per part of EMC requirement. Please do not exceed the recommended value by too much as this will have an adverse effect on signal quality. More information about damping resistors can be found on our application note.
