Abstract:
In the subject system for polarity detection, link initialization between a primary device and a secondary device may be performed in at least two stages, a half-duplex stage when only the primary device transmits initialization signals and any encoded handshaking signals may be set to false, and a full-duplex stage when both devices may transmit initialization signals. The secondary device may perform polarity detection during the half-duplex stage. If the secondary device determines that the polarities of the received signals are reversed, the secondary device may reverse the polarities of any signals subsequently received from, and transmitted to, the primary device. In this manner, the polarities can be corrected for both devices during the half-duplex stage by the secondary device. The secondary device may initiate the full-duplex link initialization stage, during which any handshaking signals may be exchanged, by transmitting signals to the primary device.
