The Port 1 & 2 PHY energy-detect events are capable of asserting the PME output by additionally
setting the PME_EN and ED_EN2 (Port 2 PHY) or ED_EN1 (Port 1 PHY) bits of the

Host MAC Power Management
(via the WUEN bit for wake-up frames,
and the MPEN bit for magic packets), detection of wake-up frames or magic packets causes the WUFR
and MPR bits of the HMAC_WUCSR register to set, respectively. If either of the WUFR and MPR bits
are set, the WOL_STS bit of the
and MPR bits of the HMAC_WUCSR register to set, respectively. If either of the WUFR and MPR bits
are set, the WOL_STS bit of the
will be set. These
events can enable PME output assertion by additionally setting the PME_EN bit of the
.
The IRQ interrupt output can be triggered by a wake-up frame or magic packet as described in
