BQ28Z610: read registers via I2C?

Part Number:BQ28Z610

Team,

Are there ways to read the BQ28Z610 registers to identify which "system level protection" have kicked in?
For example can BQstudio + EV2300 / EV2400 be used for that? Or do you need an external MCU board to run customer SW to access I2C?

Are the some guidelines on how to debug problems during developments?
The actual problem manifest itself with the BQ28Z610 that open/close the FET at a 25ms rate that make the pack voltage level oscillating between 3.8 and 4.2V:

Thanks in advance,

A.
