Interface clock. All interface signals are synchronous to Clock.
Bi-directional data bus, driven low by the link during idle. Bus
ownership is determined by Dir.
Direction. Control the direction of the Data bus.
Stop. The link asserts this signal for 1 clock cycle to stop the
data stream currently on the bus.
Next. The PHY asserts this signal to throttle the data.
