hi Team,

TRM (page 12) shows that one can modify the NVM of the device.

How can that be done? (e.g. to store designcapacity, designenergy, terminatevoltage, taperate parameters)

Do parameter modifications get preserved during a power cycle or after issuing a reset command?

It seems that values in NVM cannot be modified. So the host device needs to set up all needed parameters after each power cycle. Can you confirm this?

Hi,

I recommend sending a reset cmd anytime you update parameters. Parameters will be preserved after a reset but the BQ27427 needs to be reconfigured upon a power loss.
