Data:
The data value transmitted is dependent on the ParamType, as described above. The
CurrentValue is always packed starting at the CurrentValue [0] byte in the packet. For
multi-byte data, the values are packed LSB first(CurrentValue [0]) to MSB(CurrentValue
[0+(num bytes-1)]).
For example: Setting a given signed 16 bit parameter to a value of -300 the data array
would be packed as follows:
MC_SYS_PARAM_DEF_PKT
110
ParamId(LSB)
ParamId(MSB)
ParamType
MAX Value(LSB)
MAX Value(MSB)
MIN Value(LSB)
MIN Value(MSB)
