+ * TI_BANDGAP_FEATURE_TALERT - used when the bandgap device instance outputs

+ * TI_BANDGAP_FEATURE_MODE_CONFIG - used when it is possible to choose which
+ *      mode, continuous or one shot, the bandgap device instance will operate.
+ *
+ * TI_BANDGAP_FEATURE_COUNTER - used when the bandgap device instance allows
+ *      programming the update interval of its internal state machine.
+ *
+ * TI_BANDGAP_FEATURE_POWER_SWITCH - used when the bandgap device allows

+ *
+ * TI_BANDGAP_FEATURE_COUNTER_DELAY - used when the bandgap device features
+ *	a delay programming based on distinct values.
+ *
+ * TI_BANDGAP_FEATURE_HISTORY_BUFFER - used when the bandgap device features
+ *	a history buffer of temperatures.
+ *
+ * TI_BANDGAP_FEATURE_ERRATA_814 - used to workaorund when the bandgap device
+ *	has Errata 814
+ * TI_BANDGAP_FEATURE_UNRELIABLE - used when the sensor readings are too
