BQ40Z50-R1: Guidance on how to fix values of over voltage, under voltage etc threshold.

Hi!

i am a student currently working on 4S4P battery pack. i want some guidance on how to fix overvoltage, undervoltage etc values. are these fixed via hardware or software and how?

also, i would be grateful if some basic level literature on use of BQ40z50 (apart from datasheet) is shared.
