<p><span style="font-size:14.0pt"><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">默认情况下,</span><span lang="zh-CN" style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">复位点</span></span><span lang="en-US" style="font-weight:bold"><span style="font-family:&quot;Times New Roman&quot;">(RP)</span></span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">被设置为</span><span lang="zh-CN" style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">第一个状态</span></span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">,但可以通过</span><span lang="en-US" style="font-family:&quot;Times New Roman&quot;">&quot;</span><span lang="en-US" style="font-weight:bold"><span style="font-family:&quot;Times New Roman&quot;">SRP/CRP</span></span><span lang="en-US" style="font-family:&quot;Times New Roman&quot;">&quot;</span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">指令</span><span lang="zh-CN" style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">动态改变复位点的位置</span></span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">。</span></span></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">&nbsp;</span></span></p>

<p><span style="font-size:14.0pt"><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">值得注意的是,</span><span lang="en-US" style="font-weight:bold"><span style="font-family:&quot;Times New Roman&quot;">RESET</span></span><span lang="zh-CN" style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">和</span></span><span lang="en-US" style="font-weight:bold"><span style="font-family:&quot;Times New Roman&quot;">NEXT</span></span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">条件为</span><span lang="zh-CN" style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">同一个条件</span></span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">的情况是</span><span lang="zh-CN" style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">没有意义</span></span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">的。</span></span></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">&nbsp;</span></span></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">条件指令能够判断的条件一共有三种:</span></span></p>

<ul style="margin-left:36px; unicode-bidi:embed" type="disc">
        <li style="vertical-align:middle"><span lang="zh-CN" style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">超时</span></span></span><span lang="zh-CN" style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">:当设置了定时器,定时计数器</span></span><span lang="en-US" style="font-size:14.0pt"><span style="font-family:&quot;Times New Roman&quot;">TC</span></span><span lang="zh-CN" style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">的值达到</span></span><span lang="zh-CN" style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">零</span></span></span><span lang="zh-CN" style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">的时候,条件满足,成立。</span></span></li>
        <li style="vertical-align:middle"><span lang="zh-CN" style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">阈值比较</span></span></span><span lang="zh-CN" style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">:当启动的输入值</span></span><span lang="zh-CN" style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">高于</span></span></span><span lang="en-US" style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Times New Roman&quot;">(</span></span></span><span lang="zh-CN" style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">或低于</span></span></span><span lang="en-US" style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Times New Roman&quot;">)</span></span></span><span lang="zh-CN" style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">设定的阈值时,条件满足,成立。</span></span></li>
        <li style="vertical-align:middle"><span style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">过零检测</span></span></span><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">:当启动的输入</span></span><span style="font-size:14.0pt"><span style="font-weight:bold"><span style="font-family:&quot;Microsoft YaHei&quot;">越过零位</span></span></span><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">时,条件满足,成立。</span></span></li>
</ul>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">&nbsp;</span></span></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">以上就是命令指令和条件指令的所有特点了。</span></span></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">&nbsp;</span></span></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">如果里面有错误,希望大家能在评论中指正~~</span></span></p>

<p><span style="font-size:14.0pt"><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">以下就是</span><span lang="en-US" style="font-family:&quot;Times New Roman&quot;">35</span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">个命令指令和</span><span lang="en-US" style="font-family:&quot;Times New Roman&quot;">16</span><span lang="zh-CN" style="font-family:&quot;Microsoft YaHei&quot;">个条件指令的简介截图:</span></span></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;"><span style="font-weight:bold">命令指令</span></span></span></p>

<p></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;"><span style="font-weight:bold">条件指令</span></span></span></p>

<p></p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">最近白天各种忙,只有晚上才能搞这个,所以指令集是我一点点熬夜翻译出来的,可能会有很多纰漏和错误,希望大家发现的时候可以指出~~</span></span></p>

<p>&nbsp;</p>

<p><span style="font-size:14.0pt"><span style="font-family:&quot;Microsoft YaHei&quot;">希望可以帮助到大家吧,当然如果英语好的伙伴也可以直接阅读官方英语原文文档,这样不容易产生理解偏差~</span></span></p>
