- Memory Maps and Bit Descriptions -
Reserved
PAUSE Frame Received: Status indication that an error free, unicast, or
multicast PAUSE frame has been received.
Rx Frame Discarded: Status indication of a frame discard due to lack of
FIFO memory resource (overflow).
Note: A counter for this register is described in the statistics section.
Tx Frame Discarded: Status indication that an Under-run occurred in the
Ethernet transmit direction.
Note: In Streaming mode, when the port’s Egress FIFO goes empty
during frame transmission, an under-run occurs.
Tx Abort Frame: Status indication that a frame has been transmitted with
the error pin asserted.
Reserved
Reserved
PAUSE Frame Received Interrupt Mask: Interrupt Mask for PAUSE
Frame Received Status based interrupt. 0 = Mask Disabled, 1 = Mask
Enabled.
Rx Frame Discarded Interrupt Mask: Interrupt Mask for Rx Frame
Discarded Status based interrupt. 0 = Mask Disabled, 1 = Mask Enabled.
Tx Frame Discarded Interrupt Mask: Interrupt Mask for Tx Frame
Discarded Status based interrupt. 0 = Mask Disabled, 1 = Mask Enabled.
Tx Abort Frame Interrupt Mask: Interrupt Mask for Tx Abort Frame
Status based interrupt. 0 = Mask Disabled, 1 = Mask Enabled.
Tx Tag Error Mask: Interrupt Mask for Tx Tag Error Status based
interrupt. 0 = Mask Disabled, 1 = Mask Enabled.
Reserved
Reserved
Reserved
Tx Tag Error Status: Transmit Byte Buffer detected tag error in data
from the Egress FIFO. For example, two start of packet tags without
an end of packet tag between them would be an error. Tag errors are
counted in the Tx Abort Counter.
GMII/SMII Mode Status:
0 - SMII Mode
1 - GMII Mode
Only Ports 0 and 8 can be configured for GMII operation via external
configuration pins. The other ports will always be in SMII mode.
