The DAC LUT is a set of registers assigned to hold the pulse-density modulation profile for the associated DAC.
The values in this table are added to four times the corresponding value in the DAC OFFSET table to determine
the set point for the associated DAC. In all four DAC tables, the DAC LUT registers are formatted the same.
Beginning at -40NC, the LUT increments in 4NC steps per address until the temperature reaches 56NC, then it
increments in 2NC steps until it clamps at 102NC. See the LUT Temperature Mapping table for full register-to-
temperature mapping. Register 80h defines the -40NC to -36NC DAC LUT value, register 81h defines the -36NC to
-32NC DAC LUT value, and so on.
