UCD3138A调试问题，找不到DEVICE ID
时间：10-02

第一次使用UCD3138芯片，焊接到板子上，连接适配器，运行UCD3XXX/9XXX DEVICE GUI程序，能显示控制器版本，但是ADDRESS,DEVICE_ID,MFR_MODEL,MFR_VERSION均无显示；
另外单独运行SCAN DEVICE_ID等命令时，均提示NO DEVICE FOUND,具体信息如下所示。
从手册上看，UCD3138A的地址(PMBUS地址)是AIN0放置了一个51.1K的电阻和3300P电容的并联，然后内部电流源打开时在电阻上形成电压来决定PMBUS地址，我用示波器和万用表都没测量到该电阻上有任何电压值。
请提供指导，谢谢！

UCD3138第一使用时，芯片处于ROM mode，所以scan device in ROM mode才能找到器件
当时对UCD3138怎么使用还不熟悉，摸索一个多月，基本上知道怎么使用了。
现在在Filter上PID的控制怎么设置还不是很清楚，记得原理有个帖子上有个TI的链接，怎么也找不到了，
UCD9090第一次使用时，也是这种情况， scan device in ROM mode 才能找到器件。
但显示的是ucd3xxxx ， 请问 后续应该怎么操作，才能对它编程？
你用的是什么软件呢，如何找到这个选项，谢谢
