+使用过程中写的一个demo，可以输出任意频率和占空比的PWM

+
+[IWDT_Demo下载](./es8p5066_IWDT_demo.zip)

+```
+使用过程中写的一个demo，利用中断进行喂狗

+IWDT配置字设置（打开ESBurner软件）

+
+IWDT介绍
+
+```
+1.选择软件使能（在配置字上选择）
+2.软件进行初始化开门狗并使能
+3.当计数到0时，窗口计数器+1，
+4.当窗口计数为“2”的时候，产生中断
+5.当窗口计数器为“4”的之前没有进行喂狗操作，产生复位
+6.对 IWDT_INTCLR 寄存器进行任意写操作，IWDT 中断标志位
+均被清零，计数器重载 IWDT_LOAD 寄存器值，继续递减计
+数
+7.在 SWD 调试模式下，需要禁止 IWDT 和 WWDT，否则在调试过程中，IWDT 和 WWDT 会始终保持工作，
+可能会产生计数溢出复位，导致芯片调试异常

+# 芯片编程注意事项
+
+```
+1.由于系统控制寄存器的访问操作会影响整个芯片的运行状态，为避免误操作导致芯片运行不正常，芯片提供系统设置保护寄存器
+对时钟的选择的时候需要进行写保护关闭
+SCU_RegUnLock() ;
+SCU_RegLock() ;
+写保护开启（防止）
+
+2.对于中断标志寄存器写1清零：
+	T16N0->IF.Word = (uint32_t)0x01；
+3.GPIO的使用：
+	GPIO 端口输出电平位操作寄存器 GPIO_PADATABSR、GPIO_PBDATABSR、GPIO_PADATABCR、GPIO_PBDATABCR、GPIO_PADATABRR、GPIO_PBDATABRR 不能进行与或操作，只能按 word 写入。
+    GPIO 端口输出电平操作时建议用上述寄存器而不是端口寄存器（GPIO_PADATA 和GPIO_PBDATA）, 以避免读-修改-写情况的发生
+    系统中未使用和未封装出来的 GPIO 端口建议设置为输出固定电平并悬空，若设置为输入则不可悬空，须加上拉或下拉电阻接到电源或地。

+问题1：已解决
+
+```
+KEIL 识别不到芯片 
+ 解决1：使用Esburner软件，点击设备，点击确定（理论上芯片应该选择对应的，但是使用同类型的ES8P型号的芯片也可以，原因不明）
+ 解决2：芯片选择ES8P5066然后进行全部擦除
+ 重新将下载器拔出再插上
+ 分析原因：可能是下载器的问题
+```

+选择ESLinkII0然后电机确定，将下载器重新拔插一下即可
