This register contains the latest sensor measurement value. It has been filtered, subtracted from the IDLE register values, and
smoothened. This value is compared to the THRESH register values to determine whether the sensor is in touch or not. Filter
smoothening is determined by the TIMING.TLEVEL value. When this register is updated, ISR.SAMPLE is set by the CATB.
• RLEVEL: Integer Sensor Level
This field contains the integer part of the measured sensor discharge value.
• FLEVEL: Fractional Sensor Level
This field contains the fractional part of the measured sensor discharge value. Note that some of the LSB’s of the fractional part
might not be implemented. Refer to the Module Configuration section.
