user-specified DPA Value. See UserDpaValue. |

2-7 |

|
(*) The highest bit.7 indicates that the supply voltage is out of the recommended range. See Supply Voltage for more information about supply voltage values.
DPA Param is transparently sent with every DPA message from the [C] and thus, it controls the network behavior “on the fly”. It is not permanently stored at Nodes.
