Dynamic Signals - Xilinx RocketIO X User Manual

R
The following static signals are inputs that control the PCS interblock routing and bypass
for particular blocks, which adjust the architecture of the PCS for the user's particular
application:
•

The following static signals are inputs that control various functions, but are usually set
once at the beginning of a state machine, or after an auto-negotiation sequence. They are
typically not altered on a clock-by-clock basis:

•
The following static signals are inputs that cause either major functional resets or are used
in troubleshooting. These signals are mostly used at initialization, not during the
functional operation of the circuit:

Dynamic Signals

The following dynamic signals indicate data received on the receive bus, along with status
signals that indicate specific information about RXDATA. The set values of these signals
define the application setup by the user and are the most important after the static signals
are allocated:
