BQ20z45 Lifetime Data

In datasheet,

C.6.2.7 Lifetime Max Chg Current (Offset 12)

If the [QEN] flag is set, Lifetime Max Chg Current is updated if one of the following conditions is met:

• Internal charge current – Lifetime Max Chg Current > 100 mA

• Internal charge current > Lifetime Max Chg Current for a period > 60 seconds

• Internal charge current > Lifetime Max Chg Current AND any other lifetime value is updated.

My question is:

The Internal charge current means SBS.Current(0x0a) or internal current measurement? What is it's sample rate?

Can it save data of short current pulse (like AFE protection) or just save the data of  current monitor by gauge?

Thank!
