Description
Sets which bits of MCOMMA/PCOMMA
must be matched to incoming data and
which bits are don't cares.
When TRUE, a PCOMMA match followed
immediately by an MCOMMA match is
required for comma detection. Used to
detect A1/A2 framing characters for
SONET.
Enables detection of negative 8B/10B
commas.
Enables detection of positive 8B/10B
commas.
Limits the set of commas to which
RXCHARISCOMMA responds.
Defines comma minus to raise
RXCOMMADET and align the parallel
data.
Set to TRUE to allow minus comma
detection and alignment.
Sets the squelch clock rate based on CLKIN.
Sets the minimum differential voltage
between RXN and RXP before a signal is
recognized as a valid PCI electrical idle or a
SATA OOB signal.
Enables 5X oversampling.
Enables certain operations specific to PCI
Express.
Defines comma plus to raise
RXCOMMADET and align the parallel
data.
Set to TRUE to allow plus comma detection
and alignment.
Shared PLL configuration settings.
