To understand better, I suggest you check out the device's data sheet for Address map (page 12), Configuration Register Definition (page 13) and OT/UT Status Bits and ALARM Pin Behavior (page 15) - https://www.analog.com/media/en/technical-documentation/data-sheets/MAX31827-MAX31829.pdf > > I had the idea to make 2 channels with the exact same attributes, but with different indexes, so that I can store the overTemp related events on channel 0 and underTemp related events on channel 1.
