PME_Support.
The STE10/100A will assert PME# signal while in
the D0, D1, D2, D3hot and D3cold power state. The
STE10/100A supports Wake-up from the above five
states. Bit 31 (support wake-up from D3cold) is
loaded from EEPROM after power-up or hardware
reset. To support the D3cold wake-up function, an
auxiliary power source will be sensed during reset
by the STE10/100A Vaux_detect pin. If sensed low,
PSD3c will be set to 0; if sensed high, and if D3CS
(bit 31of CSR18) is set (CSR18 bits 16~31 are
recalled from EEPROM at reset), then bit 31 will be
set to 1.
D2_Support. The STE10/100A supports the D2
Power management state.
D1_Support. The STE10/100A supports the D1
Power management state.
Aux current. These three bits report the maximum
3.3Vaux current requirements for STE10/100A chip.
If bit 31 of PMR0 is ‘1’, the default value is 111b,
meaning the STE10/100A needs 375 mA to support
remote wake-up in D3cold power state. Otherwise,
the default value is 000b, meaning the STE10/100A
does not support remote wake-up from D3cold
power state.
The device specific initialization bit indicates
whether any special initialization of this function is
required before the generic class device driver is
able to use it.
0: indicates that the function does not require a
device-specific initialization sequence following
transition to the D0 uninitialized state.
Reserved
PME Clock. Indicates that the STE10/100A does not
rely on the presence of the PCI clock for PME#
operation.
Version. The value of 010b indicates that the
STE10/100A complies with revision 1.0a of the PCI
power management interface specification.
Next item pointer. This value is always 0h, indicating
that there are no additional items in the capabilities
list.
