The interrupt functionality is only available for digital values from the SSC-calculation unit – raw values cannot be monitored by the interrupt

feature. Figure 3.1 and Figure 3.2 show the different setup options and the respective response at the EOC pin. The use of the interrupt

register Interface Configuration), the EOC-level continuously represents the respective SSC-measurement result. For single or oversample

measurement requests without cyclic operation, the EOC output signal is reset to logical zero at the beginning of each new measurement, even

though the interrupt thresholds are established correctly (setting EOC to logical one or zero is dependent on interrupt setup) at the end of each

measurement.
