The Tracking Error LUT is set of registers assigned to hold the temperature profile for the APC reference DAC. The values in this
table combined with the APC bits in the Comp Ranging register (Table 02h, Register 8Dh) determine the set point for the APC loop.
The temperature measurement is used to index the LUT (T INDEX, Table 02h, Register 81h) in 4°C increments from -40°C to
+100°C, starting at register 80h in Table 05h. Register 80h defines the -40°C to -36°C APC reference value, register 81h defines
-36°C to -32°C APC reference value, and so on. Values recalled from this EEPROM memory table are written into the APC DAC
(Table 02h, Register 83h) location that holds the value until the next temperature conversion. The part can be placed into a manual
mode (APC-EN bit, Table 02h, Register 80h), where APC DAC can be directly controlled for calibration. If tracking error
temperature compensation is not required by the application, program the entire LUT to the desired APC set point.
