Datasheet
Data Register
The data register is an 8-bit read only register that provides a mechanism for the 82551ER 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.
