GPIO PME Enable
Setting this bit enables the assertion of the GPIO0 or GPIO8 pin, as a result of a Wakeup (GPIO) pin,
Magic Packet, or PHY Link Up. The host processor may use the GPIO0/GPIO8 pin to asynchronously
wake up, in a manner analogous to a PCI PME pin. GPIO0 signals the event when operating in Internal
PHY mode, while GPIO8 signals the event when operating in External PHY mode. Internal or External
PHY mode of operation is dictated by the
0 = The device does not support GPIO PME signaling.
1 = The device supports GPIO PME signaling.
Note:
GPIO PME Configuration
This bit selects whether the GPIO PME is signaled on the GPIO pin as a level or a pulse. If pulse is
selected, the duration of the pulse is determined by the setting of the
byte. The level of the signal or the polarity of the pulse is determined by the
this flag byte.
0 = GPIO PME is signaled via a level.
1 = GPIO PME is signaled via a pulse.
Note:
GPIO PME Length
When the
pulse on the GPIO pin, this bit determines the duration of the pulse.
0 = GPIO PME pulse length is 1.5 mS.
1 = GPIO PME pulse length is 150 mS.
Note:
GPIO PME Polarity
Specifies the level of the signal or the polarity of the pulse used for GPIO PME signaling.
0 = GPIO PME signaling polarity is low.
1 = GPIO PME signaling polarity is high.
Note:
GPIO PME Buffer Type
This bit selects the output buffer type for GPIO0/GPIO8.
0 = Open drain driver / open source
1 = Push-Pull driver
Note:
Note:
GPIO PME WOL Select
Three types of wakeup events are supported; Magic Packet, PHY Link Up, and Wakeup Pin(s) asser-
tion. Wakeup Pin(s) are selected via the GPIO Wakeup Enables specified in bytes 1Eh and 1Fh of the
EEPROM. This bit selects whether Magic packet or Link Up wakeup events are supported.
0 = Magic packet wakeup supported.
1 = PHY linkup wakeup supported. (not supported in External PHY mode)
Note:
Table 5.3
When this bit is 0, the remaining GPIO PME parameters in this flag byte are ignored.
