Serial Port Lane Ordering Select
SP_RX_SWAP
I, LVTTL,
PD
Configures the order of 4x receive lanes on serial
ports[0,6].
0 = A, B, C, D
1 = D, C, B, A
Must remain stable for 10 P_CLK cycles after
HARD_RST_b is de-asserted in order to be
sampled correctly.
This signal is ignored after reset.
Note: Ports that require the use of lane swapping
for ease of routing will only function as 4x mode
ports. The re-configuration of a swapped port to
dual 1x mode operation results in the inability to
connect to a 1x mode link partner.
No termination required.
Internal pull-down can be used
for logic 0. Pull up7 to VDD_IO
through 10K if external pull-up is
desired.
Pull down to VSS_IO through a
10K resistor if an external
pull-down is desired.
SP_TX_SWAP

Clock and Reset
P_CLK
I, LVTTL
This clock is used for the register bus clock.
The nominal frequency of this input clock is
100 MHz.
For more information on programming the P_CLK
operating frequency, refer to

No termination required.
