when the TCK or TDO pin, see screenshot datashhet below, is configured as an output GPIO for either push-pull or open-drain - Does it requirea an external pull-up voltage/resistor? Thanks, Tim

Hello Tim,
TCK and TDO pins are not open drain, there is no need for external pull-up resistor when configured as output GPIO.
