Datasheet

Figure 5.2 flowcharts PME operation while in Internal PHY Mode. The following conditions hold:

EEPROM Configuration:

ï® GPIO PME Enable = 1 (enabled)

ï® GPIO PME Configuration = 0 (PME signaled via level on GPIO pin)

ï® GPIO PME Length = 0 (NA)

ï® GPIO PME Polarity = 1 (high level signals event)

ï® GPIO PME Buffer Type = 1 (push-pull)

ï® GPIO PME WOL Select = 0 (Magic Packet wakeup)

ï® GPIO10 Detection Select = 0 (Active-low detection)

ï® Power Method = 1 (self powered)

ï® MAC address for Magic Packet

PME signaling configuration (as determined by PHY Mode):

ï® GPIO0 signals PME

ï® GPIO1 is PME_MODE_SEL

Note: A POR occurring when PME_MODE_SEL = 1 and an EEPROM present with the GPIO PME

Enable set results in the device entering PME Mode.
