About that point, I confirm my first guess. I saw a number of dumps of
that chipset, it turns out that register 0x53 always holds 0x55 or 0x64,
and is constant over subsequent dumps, while the value at 0x26 is not.
So my belief is that the register 0x53 holds the limit, but the data
sheet is wrong about the possible values, which are 85 and 100 degrees,
not 85 and 90.

I still don't know if it is possible to write to this register to change
the value.
