What are IMP channels?
Honestly? Well, it's called like that. I don't have any clear description of that
and not even datasheets are unrolling the meaning of "IMP". So.. I don't know.
What I know is what I wrote in the driver, and this is:
* IMP has IBAT and VBAT ADCs
* It needs different handling from the other ADCs, as shown.
...and nothing else :-(
I could speculate with confidence that this means IMPedance (since it's ADC).
From MTK6329 datasheet:
"The hardware also includes necessary modes to allow for simultaneous
current and voltage measurement
which can be utilized to estimate the battery impedance."
And googling in vendor trees also suggests the same.
That does make a lot of sense. Thanks for that, I don't have the 6329 datasheet.
Great, one more piece added to the puzzle!
Cheers,
Angelo
