BQ40Z50-R1: 数据读取不稳定，会偶尔出现异常值

您好，正在询问更了解这款芯片的TI工程师，稍后回复。

您好，What is the clock frequency being used? Also what is the pull-up strength for the bus? Can you also confirm if the abnormal value is being read both by the host and the logic analyzer? Sometimes the analyzer will have additional filters which will not be what BQStudio/host reads

Thanks for your reply, at first, the clock frequnency is about 76kHz, the pull-up resistance is 4.7K, and I also confirm thoes abnormal values are all appearing both by the host and the analyzer at the same time, otherwise, I imitate the timing sequence which I catched by logic analyzer, implemented the base command and 0x44 command, in other words, the timing sequence I used should be ok, the bq40z50 is also ok since the data showed by the bqstudio is ok, so only the link maybe someting wrong?

您好，已经在E2E英文论坛发帖，请继续关注。
