06h (PHY Data)

This object stores counters of power line frames transmitted or received by the ST7580 in

compliance with physical frame features. It can be read or erased only.

4.2.7

07h (DL Data)

This object stores counters of power line frames transmitted or received by the ST7580 in

compliance with data link frame features. It can be read or erased only.
