ROCKWELL PROPRIETARY INFORMATION
1167
7.1.1.17
Max Latency
This read-only register indicates how often the device needs access to the PCI Bus, in 250 ns units. This register defaults to
0x00 for all functions.
7.1.1.18
Capability ID
This register identifies the type of capability described by the Capabilities List Data Structure pointed to by the Cap_Ptr
register. This register is hard wired to 0x01 to indicate PCI Power Management.
7.1.1.19
Next Capability Pointer
This register points to the next Capabilities List Data Structure. It is set to 0x00 to indicate that no further structures exist in
the configuration space.
7.1.1.20
Power Management Capabilities
This register provides information on the capabilities of the function related to power management. Its value at reset defaults
to 0x0201 for the Audio function, 0xE411 for the Modem function and 0x0401 for the joystick function. Several of the bits in
this register can be subsequently loaded from the PnP EEPROM. See the PCI Configuration EEPROM Interface section for
more details. The register bits are defined as follows:
Power Management Capabilities Bits
Bits
R/W/C
Description
15:11
r
PME_Support. Indicates the power states in which the function may assert PME#:
XXXX1 - PME# can be asserted from D0
XXX1X - PME# can be asserted from D1
XX1XX - PME# can be asserted from D2
X1XXX - PME# can be asserted from D3hot
1XXXX - PME# can be asserted from D3cold
10
r
D2_Support. A 1 indicates support for the D2 power management state.
9r
D1_Support. A 1 indicates support for the D1 power management state.
8:6
r
Reserved.
5r
DSI (Device Specific Initialization). A 1 indicates that the function requires a device specific initialization sequence
following transition to the D0 uninitialized state before the generic class device driver is able to use it.
4r
Auxiliary Power Source. This bit is only meaningful if the function supports PME# in the D3cold state (bit15=1). If bit
15 is 0, this bit must also be 0. If this bit is 1, then this function’s support for PMD# in D3cold requires auxiliary power
supplied by the system by way of a proprietary delivery vehicle. If bit 15 is 1 and this bit is 0, the function is able to
supply its own aux power source.
3r
PME Clock. A 1 indicates that the function relies on the PCI clock for PME# operation. A 0 indicates that no PCI clock
is required for PME# generation. functions that do not support PME# must return a 0.
2:0
r
Version. A value of 001 indicates that this function complies with Revision 1.0 of the PCI Power Management
Interface Specification.
r = readable, w = writeable, c = clearable by writing ‘1’
