Power Management Registers (PM—D31:F0)
The power management registers are distributed within the PCI Device 31: Function 0
space, as well as a separate I/O range. Each register is described below. Unless
otherwise indicate, bits are in the main (core) power well.
Bits not explicitly defined in each register are assumed to be reserved. When writing to
a reserved bit, the value should always be 0. Software should not attempt to use the
value read from a reserved bit, as it may not be consistently 1 or 0.
Power Management PCI Configuration Registers
(PM—D31:F0)
Table 10-9
It includes only those registers dedicated for power management. Some of the
registers are only used for Legacy Power management schemes.
