6.5. PCI Power Management Functions
The RTL8100C(L) complies with ACPI (Rev 1.1), PCI Power Management (Rev 1.1), and the Device
Class Power Management Reference Specification (V1.0a), such as to support an Operating
System-Directed Power Management (OSPM) environment. To support this, the RTL8100C(L) provides
the following capabilities:
The RTL8100C(L) can monitor the network for a Wakeup Frame (AMD Magic Packet, LinkChg,
Microsoft wake-up frame), and notify the system via PME# should such a packet or event arrive.
Then the system can be restored to a working state to process incoming jobs.
The RTL8100C(L) can be isolated from the PCI bus automatically via the auxiliary power circuit when
the PCI bus is in B3 state, i.e. the power on the PCI bus is removed. The RTL8100C(L) can be disabled
when needed by pulling the isolate pin low to 0V.
6.5.1. Power Down Mode
When the RTL8100C(L) is in power down mode (D1 ~ D3):
The Rx state machine is stopped and the RTL8100C(L) monitors the network for wakeup events. The
RTL8100C(L) will not reflect the status of any incoming packets in the ISR register and will not receive
any packets into the Rx FIFO.
The FIFO status and the packets that are already in the Rx FIFO before entering power down mode are
held by the RTL8100C(L) during power down mode.
Transmission is stopped. PCI bus master mode is stopped. The Tx FIFO buffer is held.
After restoration to a D0 state, PCI bus master mode transfers data to the Tx FIFO that was not moved
into the Tx FIFO before the last break. A packet that was not transmitted completely before power down
mode is transmitted again.
D3cold_support_PME bit (bit15, PMC register) & Aux_I_b2:0 (bit8:6, PMC register) in PCI
configuration space
If 9346 D3cold_support_PME bit (bit15, PMC) = 1, the above 4 bits depend on the existence of
Aux power.
If 9346 D3cold_support_PME bit (bit15, PMC) = 0, the above 4 bits are all 0’s.
Examples:
1. 9346 D3c_support_PME = 1
If Aux. power exists, then PMC in PCI config space is the same as 9346 PMC,
i.e. if 9346 PMC = C2 F7, then PCI PMC = C2 F7.
Aux. power is absent, then PMC in PCI config space is the same as 9346 PMC except the above
4 bits are all 0’s. I.e. if 9346 PMC = C2 F7, then PCI PMC = 02 76.
Note: In this case, if wakeup support is desired when the main power is off, it is suggested that the
EEPROM PMC be set to: C2 F7 (Realtek default value). It is not recommended to set the D0_support_PME
bit to 1.
