COMMA_10B_ENABLE_0
COMMA_10B_ENABLE_1
Sets which bits of MCOMMA/PCOMMA
must be matched to incoming data and
which bits are don't cares.
Configurable Comma
Alignment and Detection
(page 151)
COMMA_DOUBLE_0
COMMA_DOUBLE_1
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.

(page 151)
MCOMMA_DETECT_0
MCOMMA_DETECT_1
Set to TRUE to allow minus comma
detection and alignment.

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.
RX OOB/Beacon Signaling
