reset trst

Reset是一种用于将系统恢复到初始状态的信号。在这里，reset可以指代多个信号，包括nSRST、TRST和nRST。其中，nSRST是可选项，用于同步TCK信号的产生；TRST是测试复位输入，用于对TAP Controller进行复位；nRST是与目标板上的系统复位信号相连，可直接对目标系统进行复位。这些信号的作用是将系统恢复到初始状态，并在测试或调试过程中起到重要的作用。为了避免误触发，通常需要在目标端加上适当的上拉电阻。 <span class="em">1</span><span class="em">2</span><span class="em">3</span>
