Ethernet MAC (EMAC) Registers
Description
Allow the MAC to receive tagged MAC control
packets.
–
When set, an internal loopback path is enabled
from the transmit MAC to the receive MAC. This
bit is provided for diagnostic purposes only.
11: Obsolete (Was TBI)
10: 1000BT(Copper) GMII or SerDes 1000 mode
01: 10/100BT(Copper) MII or SerDes 10/100
mode
00: None
When set, the MII/GMII interface is configured to
operate in half-duplex mode and the CSMA/CD
state machines in the MAC are set to half-duplex
mode.
When this bit is set to 1, the MAC state machine
is reset.
This is a self-clearing bit.
Description
–
–
When this bit is set, the WOL signal is asserted
when an interesting packet is detected.
Transmit Statistics block has overrun.
Generates an attention when enabled.
Receive Statistics block has overrun.
Generates an attention when enabled.
Output Data Interface block has an overrun or
underrun.
Will generate attention when enabled.
Clear this attention using the Transmit Status
register.
Auto-polling interface needs service.
Generates an attention when enabled. Clear this
attention using the Auto-polling Status register
Management interface is signaling an interrupt
Generates an attention when enabled.
