大家在调试UCD3028和UCD3138时，经常会遇到这样的需求：想随时了解一些变量和寄存器的值，以判断程序运行的情况。
使用Memory debugger可以很容易的实现该功能。请参考附件的应用笔记。
怎么找到Memory Debugger
Memory Debugger是德州仪器数字电源设计调试工具Fusion Digital Power Designer（下载地址：http://www.ti.com/fusiongui，请下载最新版本，早期版本不支持Memory Debugger功能）的一部分，主要用来读写UCD3xxx内部全局变量和寄存器的值。Memory Debugger界面如图1所示。如果是第一次调用Memory Debugger，需要输入密码“forestln”。
那么如何调出Memory Debugger工具，有两条途径：一是执行Fusion Design Online可执行文件（桌面直接双击Fusion Design Online快捷方式，如果没有创建桌面快捷方式，在开始菜单中找到Texas Instruments Fusion Digital Power Designer目录下的Fusion Digital Power Designer，点击即可），然后就可以在Fusion Design Online上的Tools菜单下面找到Memory Debugger项，如图2所示；二是执行UCD3xxx & UCD9xxx Device GUI可执行文件（桌面直接双击UCD3xxx & UCD9xxx Device GUI快捷方式，如果没有创建桌面快捷方式，在开始菜单中找到Texas Instruments Fusion Digital Power Designer\Device GUIs目录下的UCD3xxx & UCD9xxx Device GUI，点击即可）,Memory Debugger在图中红圈处。
UCD3xxx包含UCD3028和UCD3138两个系列，是TI大力推广的数字电源，可以用来设计PFC控制，高压400V转48V或12V，48V转28V或12V等多个隔离电源场景。
在RRU中应用尤为有优势。
Neil, 请问下使用memory debugger时寄存器SysRegs无法读取是什么原因，如何读取寄存器SysRegs得值？

请问怎样使用Memory Debugger观察自定义变量的值，谢谢！
需要将其定义为外部变量。
是定义为外部变量，那怎样才能添加到Memory Debugge的Watch List从而观察数据变化！
