| /** \addtogroup macb_module Ethernet MACB Driver | |
| *@{ | |
| * Implement EMAC PHY driver, that initialize the PHY to prepare for | |
| * ethernet transfer. | |
| * | |
| * \section Usage | |
| * -# EMAC related pins and Driver should be initialized at first. | |
| * -# MAC address is set via EMAC_SetAddress(). | |
| * -# Initialize MACB Driver instance by invoking MACB_Init(). | |
| * -# Initialize PHY connected via MACB_InitPhy(), PHY address is | |
| * automatically adjusted by attempt to read. | |
| * -# Perform PHY auto negotiate through MACB_AutoNegotiate(), so | |
| * connection established. | |
| * -# Setup link speed by MACB_GetLinkSpeed() so link speed and | |
| * duplex mode is desided. | |
| * -# Now its time to send/receive ethernet packets via EMAC Driver | |
| * - EMACD_Poll(): Polling received packets. | |
| * - EMACD_Send(): Send a packet. | |
