0x0B9 KR4 FEC
Corrected
Blocks, Lane
2
[31:0] Maintains count of corrected FEC blocks on
Lane 2, saturating (not rolling over) at 2 32 -1.
Resets to 0 when read. Refer to Clause 74.8.4.1 of
IEEE Std 802.3ap-2007.

0x0BA KR4 FEC
Uncorrected
Blocks, Lane
2
[31:0] Maintains count of uncorrected (uncorrectable)
FEC blocks on Lane 2, saturating (not rolling
over) at 2 32 -1. Resets to 0 when read. Refer to
Clause 74.8.4.2 of IEEE Std 802.3ap-2007.

0x0BB
This register is the equivalent of register 0xB2 for Lane 3. (Refer to 10GBASE-KR
PHY Register Definitions ).

[31:0] Maintains count of corrected FEC blocks on
Lane 3, saturating (not rolling over) at 2 32 -1.
Resets to 0 when read. Refer to Clause 74.8.4.1 of
IEEE Std 802.3ap-2007.

0x0C0 Override AN
Channel
Enable
[6]
Overrides the auto-negotiation master channel
that you set with the Auto-Negotiation Master
parameter, setting the new master channel
according to the value in register 0xCC[3:0].
While 0x0C0[6] has the value of 1, the channel
encoded in 0xCC[3:0] is the master channel.
While 0xC0[6] has the value of 0, the master
channel is the channel that you set with the
Auto-Negotiation Master parameter.

FEC_F[1:0]
[26:25
]
Received FEC ability bits. Bit [26] is FEC
requested and bit [25] is FEC ability. FEC
(F0:F1) is encoded in bits D46:D47 of the base
Link Codeword in Clause 73 AN. F0 is FEC
ability and F1 is FEC requested. Refer to Clause
73.6.5 of IEEE Std 802.3ap-2007.
