BQ34Z100 Register question

Customer has this question:

I have another question on the BQ34Z100-G1 part.  I am writing a test application to read the current sense value from the part in order to verify my charging circuitry.  Right now I am only able to successfully read the AverageCurrent() (register 0x0A/0x0B).  While this is good, the averaging takes a long time to reach steady state and is too slow for a factory test.  The part datasheet shows a non-average Current() register at 0x10/0x11 but every time I read this I get back all 0000’s.  I have used the TI BQ Evaluation Software (v0.9.90) and it correctly reads out the Current() value but I can’t tell how or where it is getting the data.  When I use the I2C Pro function and read 0x10/0x11 I again get all zeros.  Using the BQEval Studio also shows all zero’s for the Current() registers.


Any idea how I can get this information using an external I2C device?
