\brief The QKnx2ByteUnsignedValue class is a datapoint type with a 2-byte
unsigned value.
This is a fixed size datapoint type with the length of 2 bytes.
It is a base class for the following datapoint types:
\list
\li \c QKnxBrightness - Brightness in LUX
\li \c QKnxLengthMilliMeter - Length in millimeters
\li \c QKnxPropDataType - Property data type
\li \c QKnxTimePeriod10Msec - Time in 10 milliseconds
\li \c QKnxTimePeriod100Msec - Time in 100 milliseconds
\li \c QKnxTimePeriodHrs - Time in hours
\li \c QKnxTimePeriodMin - Time in minutes
\li \c QKnxTimePeriodMsec - Time in milliseconds
\li \c QKnxTimePeriodSec - Time in seconds
\li \c QKnxUEICurrentMilliA - Current in milliampers (no bus poser
supply functionality available)
\li \c QKnxValue2Ucount - Pulses
\endlist
Integer values from 0 to 65 535 can be encoded in this datapoint type.
