BQ78PL114 SMBUS interface

Other Parts Discussed in Thread: BQ2085, BQ78PL114

We are having problems communicating with the BQ78PL114 chip. This is an embedded application with C code on which we have implemented the SMBus link to the battery pack. We tested the code successfully with an older battery pack, using the BQ2085 chip.

Our question is, is the problem with the CRC? We have not implemented CRC and the BQ78PL114 chip manual speaks about it only communicating with CRC, although it is not that clear (p47).

The manual, p47 also speaks about changing the Specificatinoinfo() bits 4..7 to 0010. Is this necessary and how can we change it, it is locked.

Regards,
