[a]All time values shown are typical; for the worst case values, multiply by 1.1 (nominal frequency ±10%). See section 10.2 for additional

timing factors.

12.3 Temperature Analog Front End Configuration (T_Config, EEPROM Word 11HEX)

This register is loaded immediately before a capacitance measurement is taken, so a power cycle is not needed for changes to take effect.

010BIN

CDC_Reference

CDC reference capacitor selection. The factory settings are set for a

full-span temperature range from -40°C to +125°C.

Note: Do not change this setting from the factory setting unless a

different temperature range is needed.

5:3

010BIN

CDC_Offset

CDC offset capacitor selection. The factory settings are set for a full-

span temperature range from -40°C to +125°C.

Note: Do not change this setting from the factory setting unless a

different temperature range is needed.

8:6

110BIN

Temp_Trim

Trim setting used for the temperature measurement. The factory

settings are set for a full-span temperature range from -40°C to

+125°C.

Note: Do not change this setting from the factory setting unless a

different temperature range is needed.
