26.6.10 MAC Remote wake-up frame filter register
This is the address through which the remote Wake-up Frame Filter registers
(WKUPFMFILTER) are written/read by the Application. WKUPFMFILTER is actually a
pointer to eight (not transparent) such WKUPFMFILTER registers. Eight sequential Writes
to this address (0x028) will write all WKUPFMFILTER registers. Eight sequential Reads
from this address (0x028) will read all WKUPFMFILTER registers. See
for details.
Remark:
Do not use bit-banding for this register.
26.6.11 MAC PMT control and status register
The PMT control and status registers programs the request wake-up events and monitors
the wake-up events. See
for details.

Power-down
This register field can be read by the application (Read), can be set to 1 by the
application with a register write of 1 (Write Set), and is cleared to 0 by the core (Self
Clear). The application cannot clear this type of field, and a register write of 0 to this
bit has no effect on this field.
When set, all received frames will be dropped. This bit is cleared automatically when
a magic packet or Wake-Up frame is received, and Power-Down mode is disabled.
Frames received after this bit is cleared are forwarded to the application.This bit must
only be set when either the Magic Packet Enable or Wake- Up Frame Enable bit is set
high.

Magic Packet Received
This register field can be read by the application (Read), can be set to 1 by the
Ethernet core on a certain internal event (Self Set), and is automatically cleared to 0
on a register read. A register write of 0 has no effect on this field.
When set, this bit indicates the power management event was generated by the
reception of a Magic Packet. This bit is cleared by a Read into this register.
