      <description>&lt;P&gt;When initializing, use Wdg_43_fs23_SetMode to set the mode of the watchdog to FAST. After a period of time, it was set to OFF mode again. I found that the watchdog could not be turned off, because the FS_WDW_CFG register WDW_EN bit configured in OFF mode is 1. If it is set to 0, the watchdog can be turned off. Is this abnormal?&lt;/P&gt;</description>

&lt;P&gt;你是想要disable WD的功能当芯片进入normal模式以后对吧？&lt;/P&gt;</description>

      <description>&lt;P&gt;这个WD 关闭的时间节点只有在INIT也就是初始化的时候配置WDW_PERIOD 为’0‘去关闭它，只有这样进入normal模式以后才是WD 才是OFF的状态，但每次reset都要这样在INTI的阶段把它关掉&lt;/P&gt;</description>

      <description>&lt;P&gt;我使用的FS23驱动版本是1.0.0，RTD驱动版本是5.0.0。如果上面的情况下无法关闭看门狗，那驱动上是不是应该修改一下：&lt;/P&gt;&lt;P&gt;1、EB Tresos生成的OFF模式配置WDW_EN位是不是应为“0”，即超时看门狗；&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="_0-1734594429372.png" style="width: 400px;"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/316671i1EF40A4C2A2C3660/image-size/medium?v=v2&amp;amp;px=400" role="button" title="_0-1734594429372.png" alt="_0-1734594429372.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;2、SBC驱动代码中切换模式时，应该同时修改PERIOD位和WDW_EN位：&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="_1-1734594598614.png" style="width: 400px;"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/316672iE06133F6475D25DD/image-size/medium?v=v2&amp;amp;px=400" role="button" title="_1-1734594598614.png" alt="_1-1734594598614.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;你可以理解为period设定为0是无限制时间，然后后面那个是WD的类型，0是timeout，1是window型的。&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="guoweisun_0-1734594764139.png" style="width: 400px;"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/316673iF3EDBC031B12E70E/image-size/medium?v=v2&amp;amp;px=400" role="button" title="guoweisun_0-1734594764139.png" alt="guoweisun_0-1734594764139.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;他并不是说WD 真正的off了，只是说给你无限的时间去写对的seed喂狗，因为你后面还要喂狗来减error counter的值到0，才能释放FSXB进入normal模式。&lt;/P&gt;</description>

      <description>我理解你的意思，但我实测就是设置OFF模式后，如果停止喂狗，就会出现看门狗复位，关于设置WDW寄存器，我在早期0.8.0版本上看到的是配置所有位，但0.9.0和1.0.0是只配了WDW_PERIOD位的。</description>

      <description>&lt;P&gt;那倒不会这样，假如你disable了这个WDW_PERIOD，然后WDW_WIN选择默认的timeout 跟Window都应该是一样的。&lt;/P&gt;
&lt;P&gt;你可以试试全部都配置看看结果，一定是在INIT初始化阶段配置才有效关于这个WDW_PERIOD setting as ’0000‘&lt;/P&gt;</description>

      <description>&lt;P&gt;我已经找到这个问题的原因了：在调用SetMode接口设置OFF后，需要成功刷新一次看门狗，新的看门狗周期（无限窗口）才会生效。我之前用的是超时看门狗，所以设置OFF模式后直接刷新看门狗就可以了。但是后来改成了窗口看门狗，就不能直接刷新看门狗，需要在合理的窗口时间进行刷新。&lt;/P&gt;&lt;P&gt;但是我在查看设置OFF的SPI数据时有个疑惑，在Sbc_fs23_DisableWatchdog()这个函数内部，对FS_WDW_CFG寄存器进行了读-写-读，确认修改周期对之后设置LOCK_INT位退出INIT状态。&lt;/P&gt;&lt;P&gt;可后面又一次对FS_WDW_CFG寄存器进行了读-写-读，这是不是重复的操作？此时如果不在INIT状态，会不会有什么问题？&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="WeiCh_0-1734938013111.png" style="width: 400px;"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/317006i840A2B37FFCF3B5D/image-size/medium?v=v2&amp;amp;px=400" role="button" title="WeiCh_0-1734938013111.png" alt="WeiCh_0-1734938013111.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

&lt;P&gt;退出INIT状态以后假如进入normal模式了 对&lt;SPAN&gt;FS_WDW_CFG操作就是要把他重新打开配置，意味着他还想用这个WD供能但是不能设置period在无限’0000‘的状态了。&lt;/SPAN&gt;&lt;/P&gt;</description>
