BQ76940: Technical issues

Hi Zhonghui,

In the document it says that they occasionally read a CC value of 0xFF00. 

Do they normally read values of 0x0000 and 0xFFFF (0 and -1)? Is it possible they are reading the first byte from one sample and the second byte from the next current reading which could result in 0xFF00?

When reading the CC, the device will return an atomic value if both bytes are read at the same time using address-increment. So they should just read 16 bits from 0x32 instead of doing 2 separate reads.

Best regards,

Matt
