Clock Data Recovery Control
The CDR control feature is used for the L0s fast exit when operating in PIPE Gen3 mode. Upon detecting
an Electrical Idle Ordered Set (EIOS), this feature takes manual control of the CDR by forcing it into a
lock-to-reference mode. When an exit from electrical idle is detected, this feature moves the CDR into
lock-to-data mode to achieve fast data lock.
