Heartbeat error. A heartbeat was not detected within the heartbeat window following a
transmission.
Babbling receive error. A frame was received with length in excess of MAX_FL bytes.
Babbling transmit error. The transmitted frame length has exceeded MAX_FL bytes. This
condition is usually caused by a frame that is too long being placed into the transmit data
buffer(s). Truncation does not occur.
Graceful stop complete. A graceful stop, which was initiated by setting X_CTRL[GTS], is now
complete. This bit is set as soon as the transmitter has finished transmitting any frame that
was in progress when GTS was set.
Transmit frame interrupt. A frame has been transmitted and that the last corresponding buffer
descriptor has been updated.
Transmit buffer interrupt. A transmit buffer descriptor has been updated.
Receive frame interrupt. A frame has been received and the last corresponding buffer
descriptor has been updated.
Receive buffer interrupt. A receive buffer descriptor has been updated.
MII interrupt. The MII has completed the data transfer requested.
FEC bus error. A bus error occurred when the FEC was accessing an internal bus.
Unmasked interrupt status. An interrupt is currently being asserted to the interrupt controller.
This bit is not maskable.
Reserved, should be cleared.
