PIICX: TxMode RxMode ClkSource Mask
BufSize:32.0mS Center:No Fill:99% ()
The Fill Status is a read-only status of buffer depth, reported as a percentage:
• If the Fill Status is decreasing (approaching 0%), then the Rx traffic is arriving too slowly for the
Rx Clock setting, causing a data underflow.
• If the Fill Status is increasing (approaching 100%), then the Rx traffic is arriving too quickly for
the Rx Clock setting, causing a data overflow.
If this value indicates a data underflow or overflow, then use the  arrow keys to select Yes
to re-center the Rx Buffer depth to 50%.
