| * Provides the interface to configure and use the GMAC peripheral. | |
| * | |
| * \section gmac_usage Usage | |
| * - Configure Gmac::GMAC_NCFG with GMAC_Configure(), some of related controls | |
| * are also available, such as: | |
| * - GMAC_SetSpeed(): Setup GMAC working clock. | |
| * - GMAC_FullDuplexEnable(): Working in full duplex or not. | |
| * - GMAC_CpyAllEnable(): Copying all valid frames (\ref GMAC_NCFG_CAF). | |
| * - ... | |
| * - Setup Gmac::GMAC_NCR with GMAC_NetworkControl(), more related controls | |
| * can modify with: | |
| * - GMAC_ReceiveEnable(): Enable/Disable Rx. | |
| * - GMAC_TransmitEnable(): Enable/Disable Tx. | |
| * - GMAC_BroadcastDisable(): Enable/Disable broadcast receiving. | |
| * - ... | |
| * - Manage GMAC interrupts with GMAC_EnableIt(), GMAC_DisableIt(), | |
| * GMAC_GetItMask() and GMAC_GetItStatus(). | |
| * - Manage GMAC Tx/Rx status with GMAC_GetTxStatus(), GMAC_GetRxStatus() | |
| * GMAC_ClearTxStatus() and GMAC_ClearRxStatus(). | |
| * - Manage GMAC Queue with GMAC_SetTxQueue(), GMAC_GetTxQueue(), | |
| * GMAC_SetRxQueue() and GMAC_GetRxQueue(), the queue descriptor can define | |
| * by \ref sGmacRxDescriptor and \ref sGmacTxDescriptor. | |
| * - Manage PHY through GMAC is performed by | |
| * - GMAC_ManagementEnable(): Enable/Disable PHY management. | |
| * - GMAC_PHYMaintain(): Execute PHY management commands. | |
| * - GMAC_PHYData(): Return PHY management data. | |
| * - GMAC_IsIdle(): Check if PHY is idle. | |
| * - Setup GMAC parameters with following functions: | |
| * - GMAC_SetHash(): Set Hash value. | |
| * - GMAC_SetAddress(): Set MAC address. | |
| * - Enable/Disable GMAC transceiver clock via GMAC_TransceiverClockEnable() | |
| * - Switch GMAC MII/RMII mode through GMAC_RMIIEnable() | |
| * | |
| * For more accurate information, please look at the GMAC section of the | |
| * Datasheet. | |
