BQ27510-G2 question and datasheet correction.  Yes, I need to update it to a G3, but extracting data from it first.

1. What is the floating point format used for CC Gain and CC Delta?  It doesn’t appear to be IEEE 754 or the byte order is mangled.

 

I am getting very large values that are out of range.  Here is debug showing 32 byte read of calib data and subsequent decoding.

 

Double checked CC Gain = 0x7f71205c hex to floating point conversion and it shows same large value.

2.  Datasheet page 17 has incorrect offsets values for Configuration Charge Termination.   Here are correct offsets:
