Default setting. The RXSTATUS optional port presents status information for the
PIPE interface. See the Spartan-6 FPGA GTP Transceivers User Guide for more details.
The RXSTATUS optional port presents codes for the SATA COM sequence status.
Selecting this option enables certain operations specific to PCI EXPRESS, including

Integer value between 0 and 15 indicating the number of busts to define a TX COM
sequence.
This option is not available if RXSTATUS encoding format is set to PCI EXPRESS.
Integer value between 0 and 7 indicating the number of Burst sequences to declare
a COM match. This value defaults to 4, which is the burst count specified in the
SATA specification for COMINIT, COMRESET, and COMWAKE.
Integer value between 0 and 7 indicating the number of Idle sequences to declare a
COM match. Each Idle is an OOB signal with a length that matches
COMINIT/COMRESET or COMWAKE. This value defaults to 3 per the SATA
specification.
This option is not available if RXSTATUS encoding format is set to PCI EXPRESS.
