The Flow Control functionality (legacy), as defined in IEEE Standard 802.3, and the Priority Flow Control functionality, as defined in the IEEE standard 802.1Qbb, are specified by the respective standards for full-duplex applications only.
Configuration of the TEMAC allows Legacy Flow Control/Priority Flow Control functionality and Duplex mode to be configured independently. However, Legacy Flow Control/Priority Flow Control is enabled only in full-duplex mode. Ensure that the following conditions are met:
- When operating half-duplex mode, always disable Legacy Flow Control/Priority Flow Control.
- When operating in full-duplex mode, Flow Control/Priority Flow Control can optionally be enabled.
