校准BQ3060时发现芯片检测cell4电池为0V并且后面cell count数量为3不能更改,我的电路设计是4串的,IC电池电压检测脚的电压都没有问题(已确认)。请问如何设置芯片参数

恕我眼拙,真没翻到设置的位置。能否明示?软件的在电脑上运行可能有点问题启动的时候老是搜不到office的mini文件可能影响到了词条的帮助信息,现在help text链接都无法打开导致很多参数缩写都不明其意。

技术文档的第142页有相关的描述,将Operation Cfg A的CC1 C0位设置为01就是2串
CC1, CC0 — These bits configure the bq3060 for the number of series cells in the battery stack.
0,0 = Reserved
0,1 = 2 cell
1,0 = 3 cell (default)
1,1 = 4 cell
