The MAC-PHY signal interface consists of the Data Interface including an 8-bit data bus, the Control Interface, the CCA Interface and the Management Interface. The Data Interface, which is used to transfer data to and from the MAC, operates differently depending on the state of the PHY. The Control Interface is used by the MAC to control the operating state of the PHY and by the PHY to indicate TX/RX status to the MAC. The CCA Interface is used for Clear Channel Assessment status indication. The Management Interface is used to access the PHY registers.
