According to the note 1 in 9.2 Debug port pin descriptions of KE02 reference manual, we need to add external pulldown resistor for the SWD_CLK to fully support SWD protocol.
Please advise the below questions as soon as possible.
1. Please tell us recommended pulldown resistor value.
2. Please tell us restriction if we don't add external pulldown resistor.
3. Is the SWD_DIO require pullup or pulldown resistor to fully support SWD protocol?
