When performing a write operation, the first 3 LUTDAT
bits, D15, D14, and D13 are don’t care. When perform-
ing a read operation, these bits are set to the LUT data
channel tag 110. Bits D12–D7 set the size of the LUT in
binary format. Set the LUT size between 8 (001000)
and 48 (110000). Bits D6, D5, and D4 set the hysteresis

bit threshold. Using the temperature LUT as an exam-
ple, if the HYS value is 101 (16 bits) and the latest tem-
perature measurement differs from the last one by more
than 2°C, a new TLUT operation is performed and a
new TLUT value is calculated. Bits D3–D0 set the LUT
step size. See Table 28c. The step size is based on the
value of 2
STEP bits. Set the step size between 1 (2
