System Changes Power Mode Example
The PMDATASEL register loading sequence from the
serial EEPROM is as follows:
• Bits [31:24]—Data Select for D
• Bits [23:16]—Data Select for D
• Bits [15:8]—Data Select for D
• Bits [7:0]—Data Select for D
The Data_Scale register bits (PMCSR[14:13]) that
provide a scale factor value for the Data_Select value
retains four possible scale factors—0, 1, 2, and 3.
(Refer to PCI Power Mgmt. r1.1 for the scale factor
derivative values.) Each Data_Scale field requires a
2-bit register in which to store the data. The PCI 9030
provides an 8-bit hidden register, PMDATASCALE, to
store such information. The PMDATASCALE register
can be written only from the serial EEPROM and read
from the PMCSR[14:13] with the corresponding
Data_Select value in the Power Management Control/
Status register bits (PMCSR[12:9]).
The loading sequence of the PMDATASCALE register
from the serial EEPROM is as follows:
• Bits [7:6]—Data_Scale for D
• Bits [5:4]—Data_Scale for D
• Bits [3:2]—Data_Scale for D
• Bits [1:0]—Data_Scale for D

PMCSR[14:13] provides a scale factor for the
D
bits (PMDATASCALE[1:0]).
PMDATA[7:0] provides the D
Consumed value from the D
Consumed bits (PMDATASEL[7:0]).
PMCSR[14:13] provides a scale factor for the
D
bits (PMDATASCALE[7:6]).
PMDATA[7:0] provides the D
Dissipated value, from the D
Dissipated bits (PMDATASEL[31:24]).

Notes:
cycles are granted.
The PCI 9030 automatically performs a soft reset to a Local Bus
on D
values stored in the serial EEPROM.

An example of a wake-up request follows:
1. The Host writes to the PCI 9030 PMCSR
2. The PCI 9030 sends a Local Power
