Part Number:BQ27426
Hello,
I'm trying to set my custom values for certain fields, such as the Design Capacity, Design Energy, etc, but I just encountered an issue.
On the Technical Reference Manual (sluub0), on page 35, table 7-2, the last field on the State subclass is Delta Voltage, at an offset of 29, with a default value of 1. However, on page 50, section 7.4.2.3.10, the same document says offset 29 corresponds to Taper Voltage, with a default value of 4100. On page 52, section 7.4.2.3.15, Delta Voltage is once again listed with a default value of 1 at offset 29. Scanning the memory manually, I can see that the default value is 1, so it looks like it is Delta Voltage that's occupying that slot, but where is Taper Voltage located then?
Also, that subsection describes extra parameters that are not listed on table 7-2 (namely, Voltage at Charge Termination, on page 51, section 7.4.3.12, at offset 33). Which of the two sections is correct? Does this mean that the State subclass is actually two blocks wide (64 bytes), since it has a field at offset 33? Should I be storing that field to prevent it from being lost after a power loss?
Thanks
