LOSV
These registers provide the status of each individual RXDn+/- serial link.
LOSV:
The LOSV gives the Loss of Signal state. LOSV becomes logic 1 upon 2048
bit periods (13.2 µs at 155.52 Mb/s) without a signal transition in the
scrambled data. LOSV becomes logic 0 when a signal transition has
occurred in each of 16 consecutive intervals of 16 bit periods each.
LCDV:
The LCDV bit gives the Loss of Cell Delineation state. When LCDV is logic 1,
an out of cell delineation (OCD) defect has persisted for 1318 cells. LCDV
becomes logic 0 when cell delineation has been maintained for 1318 cells.
ACTV:
The ACTV bit provides the debounced state of the ACTIVE bit in the cell
prepend. ACTV reflects the state of the ACTIVE bit when it has been the
same for three consecutive valid cells.
OCDV:
The OCDV bit indicates the cell delineation state. When OCDV is logic 1, the
cell delineation state machine is in the 'HUNT' or 'PRESYNC' states and is
hunting for the cell boundaries. When OCDV is logic 0, the cell delineation
state machine is in the 'SYNC' state and cells are passed through the receive
FIFO.
