Wait Time Selection

The MCONFB register is used to set the wait time between the measurements, to configure the

subtraction option of the IC and to set the digital gain of the measurement. The subtraction option is

useful if a single readout channel is used for measuring ‘dark’ leakage current. This ‘dark’ leakage

current can be subtracted digitally from other channels on the IC to compensate for the temperature

dependent leakage current. If a measurement is running, writing MCONFB will restart the

measurement.
