DESCRIPTION

Last_Scci_phy_link_id
Physical link ID of the rx link on which the last
“analyzable” ICP cell comes. A ICP cell is
considered analyzable if
1). the current processing cycle is ICP and
2). the ICP cell is valid, and
3). the ICP cell carries a new SCCI, or the ICP
cell comes from the same link of the last
analyzed ICP cell; and
4). RX_IMA_ID matches the configured value
(or if no value is configured, the value captured
from the first ICP cell if group is
started/restarted)

RX_TRL_VALID
This indicates whether in the RX IDCC the TRL
of the current group has been turned on or not.
TRL is identified by the RX_TRL_PHY_ID field,
which is translated from the TX_TRL_ LID in the
incoming ICP cells, after it is validated by RIPP.
‘0’: Invalid. TRL off.
‘1’: Valid. TRL on.
This bit is set internally by RIPP when it first
turns on the TRL in RX IDCC (when
LSM_SYNC reaches the right state and TRL
LID has been validated). It is possible for the FE
to change the TRL_LID during normal
operations, in which case the new TRL LID will
be verified again and saved.

RESERVED
RX_TRL_PHY_ID
Receive timing reference physical link ID.
RX_TRL_PHY_ID is translated via a lookup into
the RX_PHY_TABLE using the TRL_LID field in
the incoming ICP cells, and then used to control
the Rx IDCC.
15:13
12:8
RESERVED
RX_TRL_LID
The TRL LID info captured from incoming ICP
cells.
7
DELAY_ADJUST_ACTIV
E
Indicates whether an adjust_delay procedure is
current active. Adjust delay could be started by
PM command adjust_delay, or internally by
LASR procedure.
‘0’: No delay adjustment is in progress.
‘1’: Delay adjustment is in progress.
6
DELAY_ADJUST_RDAT_ The last value of the delay_toggle bit read from
TOGGLE
RDAT group context memory. A transition on
this bit is used to determine the ongoing
adjust_delay process is finished.
