Dynamic reconfiguration clock. This clock is also used for offset cancellation
in all modes except PCIe mode.
The width of this signal is determined by the value you set in the What is the
number of channels controlled by the reconfig controller? option in the
Reconfiguration settings screen.
The width of this signal is fixed to four bits. It is independent of the value you
set in the What is the number of channels controlled by the reconfig
controller? option in the Reconfiguration settings screen.
PCIe polarity inversion control. Functionally equivalent to the RxPolarity
signal defined in PIPE specification revision 2.00. Available only in PCIe mode.
When asserted high, the polarity of every bit of the 10-bit input data to the
8B/10B decoder is inverted.
PCIe power state control. Functionally equivalent to the PowerDown[1:0]
signal defined in PIPE specification revision 2.00. The width of this signal is
2 bits and is encoded as follows:

Receiver detect or PCIe loopback control. Functionally equivalent to the
TxDetectRx/Loopback signal defined in PIPE specification revision 2.00.
When asserted high in the P1 power state with the tx_forceelecidle signal
asserted, the transmitter buffer begins the receiver detection operation. When
the receiver detect completion is indicated on the pipephydonestatus port,
this signal must be de-asserted.
When asserted high in the P0 power state with the tx_forceelecidle signal
de-asserted, the transceiver datapath is dynamically configured to support
parallel loopback, as described in
page
Forces the 8B/10B encoder to encode with a negative running disparity.
Functionally equivalent to the TxCompliance signal defined in PIPE
specification revision 2.00. Must be asserted high only when transmitting the
first byte of the PCI Express Compliance Pattern to force the 8B/10B encode
with a negative running disparity, as required by the PCIe protocol.
