Register Description:
1000X Status2 Register.
Register Offset:
0x15 at Block 0
12
CRC_ERR_DETECTE
D
RO
1 = CRC error detected since last read.
0 = No CRC error detected since last read or detection is
disabled via register 0*10h bit [7].
0
11
TX_ERR_DETECTED RO
1 = Transmit error code detected since last read
(rx_data_error state in pcs receive fsm).
0 = No transmit error code detected since last read.
0
10
RX_ERR_DETECTED RO
1 = Receive error since last read (early_end state in pcs
receive fsm)
0 = No receive error since last read
0
9
CARRIER_EXT_ERR_
DETECTED
RO
1 = Carrier extend error since last read (extend_err in pcs
receive fsm)
0 = No carrier extend error since last read
0
8
EARLY_END_EXT_DE
TECTED
RO
1 = Early end extension since last read (early_end_ext in
pcs receive fsm)
0 = No early end extension since last read
0
7
LINK_STATUS_CHG
RO
1 = Link status has changed since last read
0 = Link status has not changed since last read
0
6
PAUSE_RESOLUTION
_RXSIDE
RO
1 = Enable pause receive
0 = Disable pause receive
0
5
PAUSE_RESOLUTION
_TXSIDE
RO
1 = Enable pause transmit
0 = Disable pause transmit
0

SPEED_STATUS
RO
1X = Gigabit
01 = 100 mbps
00 = 10 mbps
0
2
DUPLEX_STATUS
RO
1 = Full-duplex
0 = Half-duplex
Note:
When the ten bit interface is selected with fiber mode
(1000-X), then half-duplex will always be reported.
0
1
LINK_STATUS
RO
1 = Link is up.
0 = Link is down.
Note:
When the ten bit interface is selected with fiber mode
(1000-X), then link will always be down
0
0
SGMII_MODE
RO
1 = SGMII mode
0 = Fiber mode (1000-X)
0
