BIT NAME
PME_SP
DESCRIPTION
PME_Support
bit 31 = 1 --- PMEB can be asserted from D3(cold) state. The
value is dependent on the auxiliary power source detection
from pin BtOEB/AuxPWR after power-on reset.
bit 30 = 1 --- PMEB can be asserted from D3 (hot). Fixed to 1.
bit 29 = 0 --- PMEB cannot be asserted from D2. Fixed to 0.
bit 28 = 1 --- PMEB can be asserted from D1. Fixed to 1.
bit 27 = 1 --- PMEB can be asserted from D0. Fixed to 1.
D2_Support
Fixed to 0. W89C841F does not support D2 Power
Management State.
D1_Support
Fixed to 1. W89C841F supports D1 Power Management
State.
3.3V Auxiliary Current
This field reports the 3.3Vaux auxiliary current requirements
for PCI function. If PM_Data_En is disable and D3 cold is not
supported, Aux_Current are fixed to 000b. IF PM_Data_En is
disable and D3 cold is supported, Aux_Current bits apply:
Bit 3.3VAux
24 23 22 Max. Current Required
1 1 1 375 mA
1 1 0 320 mA
1 0 1 270 mA
1 0 0 220 mA
0 1 1 160 mA
0 1 0 100 mA
0 0 1 55 mA
0 0 0 0 (self powered)

Current
If bit PM_Data_En loaded from EEPROM is enabled,
PM_Data field of Fe0/FPMR1 Is implemented to report the
power consumption and power dissipation of each device
state (D0, D1 and D3). So it takes precedence over 3.3Vaux
current requirement reporting. Aux_Current bits will be fixed
to 000b.
Note: The 3.3Vaux Max. auxiliary current of W89C841F is 220 mA which
should be loaded from EEPROM.
