8.2.3.6 Data register
Table 38.
Address: Value read from address 34h + 6h
Table 39.
The Data register is an optional, 1 B register that provides a mechanism for the function to
report state dependent operating data, such as power consumed or heat dissipated.

Description
Bus Power/Clock Control Enable:
1 — Indicates that the bus power or clock control mechanism as defined in
Table 39
0 — Indicates that the bus or power control policies as defined in
are disabled
When the Bus Power or Clock Control mechanism is disabled, the bridge’s
PMCSR Power State (PS) field cannot be used by the system software to
control the power or clock of the bridge’s secondary bus.
B2/B3 support for D3
to occur as a direct result of programming the function to D3
1 — Indicates that when the bridge function is programmed to D3
secondary bus’s PCI clock will be stopped (B2)
0 — Indicates that when the bridge function is programmed to D3
secondary bus will have its power removed (B3)
This bit is only meaningful if bit 7 (BPCC_EN) is logic 1.

Description
DATA: This register is used to report the state dependent
data requested by the D_S field of the PMCSR register.
The value of this register is scaled by the value reported by
the DS field of the PMCSR register.
