加10K下拉电阻,数据手册上第48页TRST管脚备注中有说明。
To ensure a proper logic level during reset when these pins are both routed out and 3−stated or not driven, it is recommended to include an
external 10 kΩ pullup/pulldown resistor to sustain the IPU/IPD, respectively.

你好,我再请问下,接1K的下拉电阻是不也可以,1k的下拉电阻是不比10K的下拉能力更强,更可靠?
