pcs_mode_rc[5:0]
Output
Specifies the PCS mode for reconfig using 1-hot encoding.
The following modes are defined:
■ 6’b000001: Auto-Negotiation mode
■ 6’b000010: Link Training mode
■ 6’b000100: 10GBASE-KR data mode
■ 6’b001000: Reserved
■ 6’b010000: Reserved

mode_1g_10gbar
Input
This signal indicates the requested mode for the channel. A 1
indicates 1G mode and a 0 indicates 10G mode.
en_lcl_rxeq
Output
Enables RX Equalization. Equivalent to Link Trained status bit
0xD2 bit0. Active high.
rxeq_done
Input
When asserted indicates that RX Equalization is complete.
This signal is
AND
ed with
rx_trained
from the 10GBASE-KR
Training State Diagram. For more information, refer to Figure
72-5 in Clause 72.6.10.4.3 of IEEE 802.3ap-2007.
