Description
IDLE
When set, during non retime mode, generates Idle on all lanes of the
redundant XAUI channel.
A/B select
When set, channel A is selected as primary else channel B acts as primary
channel.
RETIME
When set, device will go into retime mode else non retime mode. (Default 0)
XGMII Tristate
When set, puts into a high-impedance state the data outputs on the XGMII
side
Transition code
Output code to be sent during transition from A to B or B to A. When 0 FE,
when 1 LF is transmitted.

Description
IDLE composite
When high, indicates that Idle mode is selected through the REDUN-
DANCY_CONTROL register on page 56 or through the device input pin.
A_B composite
When high, indicates that lane A is selected as primary lane. It is OR ed
version of the REDUNDANCY_CONTROL register bit on page 56 and the
device input pin.
RETIME composite
When high, indicates that device is in RETIME mode. It is OR ed version of
the REDUNDANCY_CONTROL register bit on page 56 and the device input
pin.
