Data Select: This read-write register indexes the reported through the Data Register

 

 

 

 

(“Offset 308h: PWRBGT_DATA—Power Budgeting Data Register” on page 120) and selects

 

 

 

 

the Dword of the power budgeting data that must appear in the Data Register.

 

 

 

 

The index values for this register start at 0 to select the first DWord of the power budgeting

 

 

 

 

data; subsequent DWords of the power budgeting data are selected by increasing index

 

 

 

 

values. For example:

7:0

 

RW

00h

•

A value of 0 selects the DWord data starting at address 314h to appear in the Data

 

 

 

 

 

Register at offset 308h.

 

 

 

 

• A value of 1 selects the DWord data starting at address 318h to appear in the Data

 

 

 

 

 

Register.

 

 

 

 

•

(and so on)

 

 

 

 

When the Data Select field values is greater than 23, all zeros are reported in the Data

 

 

 

 

Register.
