Both the T and KLUTs contain 12-bit data. The TLUT
data is stored in two’s-complement format with decimal
values ranging from -2048/2048 (-1) to +2047/2048
(+0.9995) in steps of approximately 0.0005.
The KLUT data is stored in binary format with decimal
values ranging from 0 to +4095/4096 (0.9998) in steps
of approximately 0.0002.

The base value signifies the starting point for the LUT. The KLUT base
value is stored in binary format, with the LSB equaling 1. The TLUT base
value is stored in two’s-complement format, with the LSB equaling
+0.125°C.
