summarizes the external I/O signals for the 8-bit PIPE interface modes.
PCI Express reset signal, active low.
PIPE interface phystatus signal. Signals the completion
of the requested operation.
PIPE interface powerdown signal, Used to request that
the PHY enter the specified power state.
Input clock connected to the PIPE interface pclk signal
from the PHY. Clocks all of the status and data signals.
Depending on whether this is an SDR or DDR interface
this clock will be either 250 MHz or 125 MHz.
Source synchronous transmit clock signal for clocking
TX data and control signals going to the PHY.
Pipe interface lane 0 RX data signals, carries the parallel
received data.
Pipe interface lane 0 RX data K-character flag.
Pipe interface lane 0 RX electrical idle indication.
Pipe interface lane 0 RX polarity inversion control.
Pipe interface lane 0 RX status flags.
Pipe interface lane 0 RX valid indication.
Pipe interface lane 0 TX compliance control.
Pipe interface lane 0 TX data signals, carries the parallel
transmit data.
Pipe interface lane 0 TX data K-character flag.
Pipe interface lane 0 TX electrical idle control.
Pipe interface lane 1 RX data signals, carries the parallel
received data.
Pipe interface lane 3 RX electrical idle indication.
Pipe interface lane 3 RX polarity inversion control.
Pipe interface lane 3 RX status flags.
Pipe interface lane 3 RX valid indication.
Pipe interface lane 3 TX compliance control.
Pipe interface lane 3 TX data signals, carries the
parallel transmit data.
Pipe interface lane 3 TX data K-character flags.
