7.4.7.1 Foreground Calibration Mode

Foreground calibration requires the ADC to stop converting the analog input signals during the procedure. Foreground calibration always runs on power-up and a sufficient period of time must elapse before programming the device to ensure that the calibration is finished. Foreground calibration can be initiated by triggering the calibration engine. The trigger source can be either the CAL_TRIG pin or CAL_SOFT_TRIG (see the calibration software trigger register) and is chosen by setting CAL_TRIG_EN (see the calibration pin configuration register).
