Intel GD82559ER manual Ethernet Data Register, Data Select Data Scale Data Reported

GD82559ER — Networkin g Silicon

7.1.20Data Register

The data register is an 8-bit read only register that provides a mechanism for the 82559ER to report state dependent maximum power consumption and heat dissipation. The value reported in this register depends on the value written to the Data Select field in the PMCSR register. The power measurements defined in this register have a dynamic range of 0 to 2.55 W with 0.01 W resolution according to the Data Scale. The value in this register is hard coded in the silicon. The structure of the data register is presented below.
