BQ40Z80: ManufacturerData() structure as defined in slua868 seems different than expected

Part Number: BQ40Z80

Hi All,

Slua868 calls out the format of 0xF081 as being:

ZZYYaaAAbbBBccCCddDDeeEEffFFggGGhhHHiiIIjjJJkkKKllLLmmMMnnNNooOO

With ZZ being the 8 bit counter that increments. What I've been finding is that the incrementing byte is actually the 3rd byte being received.

I got that traceback using a beagle i2c sniffer while connected to battery management studio. I am using the BQ40Z80EVM-020, but I dont see why that would make a difference.

What are those first 3 bytes representing?
