UCD9222: UCD9222是否每次上电都要使用FUSION digital power designer重新配置?

Part Number: UCD9222

TI老师们好:

最近在设计一个基于C6678的板子,要用到UCD9222提供电压。我之前理解是我把PMBUS线引出来,利I用FUSION digital power designer,加上一个GPIO to USB 的 adapter,配置一次就可以把参数写入到UCD9222中,以后每次上电都不需要再用FUSION digital power designer去配置了。但是这个问题中TI的老师告诉我每次上电都需要配置一次UCD9222.我想确认一下是不是这样,如果是,那感觉这个芯片使用起来很麻烦啊,有点不太理解。
