6-bit Binary RX elastic buffer configuration.
Reserved. The recommended value from the 7 Series FPGAs
Transceivers Wizard should be used.
String Defer RX elastic buffer reset on comma realignment. The time
deferred is controlled by RXBUF_EIDLE_HI_CNT.
TRUE: Enables deferral of RX elastic buffer reset on comma
realignment.
FALSE: Disables deferral of RX elastic buffer reset on comma
realignment.
String RX elastic buffer address mode.
FULL: Enables the RX elastic buffer for clock correction and
channel bonding support.
FAST: Enables the RX elastic buffer for phase compensation
without clock correction and channel bonding support. This
mode is recommended for high line rates.
4-bit Binary Controls the timing of asserting the GTP transceiver internally
generated RX elastic buffer reset on electrical idle when valid data
is not present on the RXP/RXN serial lines.

String GTP transceiver internally generated RX elastic buffer reset on
channel bonding change.
TRUE: Enables auto RX elastic buffer reset on channel bonding
change.
FALSE: Disables auto RX elastic buffer reset on channel
bonding change.
String GTP transceiver internally generated RX elastic buffer reset on
comma realignment.
TRUE: Enables auto RX elastic buffer reset on comma
alignment.
FALSE: Disables auto RX elastic buffer reset on comma
alignment.
