Normal mode is the default mode of operation after power-up. In this mode, the internal modulator of the ΔΣ ADC runs at a modulator clock frequency of fMOD = fCLK / 4 = 256 kHz, where the system clock (fCLK) is provided by the internal oscillator. Normal mode offers output data rate options ranging from 20 SPS to 1 kSPS. The data rate is selected by the DR[2:0] bits in the configuration register.
