MX98725
5.3 Power Management Functions :
MX98715A complies to ACPI Version 1.0, supports
D3cold state to generate PMEB. There are basically 3
power saving modes supported, namely Remote Power-
On, Remote Wake-Up, and Sleep mode. By default,
MX98715A will enable ACPI function with the following
registers setup :
PFCS<20> ( New Capability )= 1
PFCP<7:0> ( Capability Pointer ) = 44h
PPMC<7:0> ( Capability ID ) = 1h
Please refer to PCI configuration registers for more de-
tails.
5.3.1 Remote Power-On Mode :
When AC power cord of PC is plugged into the wall
outlet, MX98715A will load the network ID from
EEPROM and enter itself into Remote Power-On mode
automatically. The host and PCI bus has no power at
this stage. As soon as a Magic packet addressed to this
network adaptor, PMEB will be asserted low to power
on the PC.
To set up the Remote Power-On ( RPO ) mode, as long
as a 5.0V standby VDD is connected into the adaptor's
isolated VDD and MX98715A will set up itself to detect
Magic packet. No registers needed to be programmed.
Simply turn off the power switch or plug in the AC power
cord of the PC that support RPO and everything else is
set automatically.
5.3.2 Remote Wake-Up Mode :
When the PC is still turned on regardless of the status
of CPU and system's status, a Magic packet can be
detected if enabled. As soon as a Magic packet ad-
dressed to the network adaptor is detected, both INTA#
and PMEB can be asserted low if registers set up as
follows :
CSR16<22> ( PME ) = 1 and
PPMCSR<8> ( PME_EN ) =1
to enable PMEB assertion.
CSR16<22> ( PME ) = 1 and
CSR7<28> ( MPIE ) = 1 to enable INTA#
assertion
5.3.3 Sleep Mode :
Set PFDA<31> ( Sleep ) = 1 will enter the chip into a
sleep mode where no TX nor RX activities can be pro-
cessed. Only PCI configuration can be accessed.
