Description
Determines whether sequences are
matched against 8B/10B decoded data or
undecoded data.
Defines the number of valid characters
required to decrement the error count by 1
for the purpose of loss-of-sync
determination.
Defines the error count required to move
the Loss of Sync state machine from the
SYNC_ACQUIRED to the SYNC_LOST
state.
Defines the behavior of the
RXLOSSOFSYNC outputs.
Selects between sliding in the PMA or in the
PCS.
Sets whether the RX_STATUS port is used
to report the status of PCI Express or SATA
features.
Selects which clock is used on the PMA side
of the RX FIFO. The default setting is
RXREC (RX recovered clock). RXUSR (RX
USRCLK) should be used when bypassing
the RX buffer.
Number of bursts required for the SATA
OOB detector to declare a COM match.
Number of idles required for the SATA
OOB detector to declare a COM match.
Sets the threshold for the SATA detector to
reject a burst in terms of squelch clock
cycles.
Sets the maximum time allowed for a
COMINIT/COMRESET idle for the SATA
detector in terms of squelch clock cycles.
Sets the maximum time allowed for a
COMWAKE idle for the SATA detector in
terms of squelch clock cycles.
Sets the threshold for the SATA detector to
reject a burst in terms of squelch clock
cycles.
Used to set the minimum time allowed for a
COMINIT/COMRESET Idle for the SATA
detector in terms of squelch clock cycles.
