I am using STM32L471 controller, I just want to ask that what is the maximum value of decoupling capacitor which can be used at JTAG SWDIO pin of controller, so that there would not be any issue during programing of controller using SWD 4MHz setting.

We have defined this JTAG-SWDIO pin as a input in our circuit, during mains as well as in battery mode. To ensure any false detection on input, we need to add a capacitor at this pin, now I just want to ask that what is the maximum value of capacitor...
