Temperature sensors — piecewise linear function

Dear reader,

A0..A5 (slope), B0..B5 (y intercept) and T0..T4 (end of range) are the coefficients documented in chapter 6.26.

I've wondered how to interpret them exactly. Assuming that the function should be near-continuosly and guessing a bit around, I came to the equation 

corrected = measured_°C * 1024 / Ax + Bx / 32 ; Tx values also to be interpreted as °C.

From the beginning I've expected the Bx to be falling, if the Ax rise. But both, A and B, rise. Is there somewhere the exact documentation on that?

Kind regards, Jochen
