AnnaBridge 171:3a7713b1edbc 446 *
AnnaBridge 171:3a7713b1edbc 447 * Note:
AnnaBridge 171:3a7713b1edbc 448 * 1. macSpecialConfig is used for a special control configuration, a logical OR of
AnnaBridge 171:3a7713b1edbc 449 * "enet_special_control_flag_t". For a special configuration for MAC,
AnnaBridge 171:3a7713b1edbc 450 * set this parameter to 0.
AnnaBridge 171:3a7713b1edbc 451 * 2. txWatermark is used for a cut-through operation. It is in steps of 64 bytes.
AnnaBridge 171:3a7713b1edbc 452 * 0/1 - 64 bytes written to TX FIFO before transmission of a frame begins.
AnnaBridge 171:3a7713b1edbc 453 * 2 - 128 bytes written to TX FIFO ....
AnnaBridge 171:3a7713b1edbc 454 * 3 - 192 bytes written to TX FIFO ....
AnnaBridge 171:3a7713b1edbc 455 * The maximum of txWatermark is 0x2F - 4032 bytes written to TX FIFO.
AnnaBridge 171:3a7713b1edbc 456 * txWatermark allows minimizing the transmit latency to set the txWatermark to 0 or 1
AnnaBridge 171:3a7713b1edbc 457 * or for larger bus access latency 3 or larger due to contention for the system bus.
AnnaBridge 171:3a7713b1edbc 458 * 3. rxFifoFullThreshold is similar to the txWatermark for cut-through operation in RX.
AnnaBridge 171:3a7713b1edbc 459 * It is in 64-bit words. The minimum is ENET_FIFO_MIN_RX_FULL and the maximum is 0xFF.
AnnaBridge 171:3a7713b1edbc 460 * If the end of the frame is stored in FIFO and the frame size if smaller than the
AnnaBridge 171:3a7713b1edbc 461 * txWatermark, the frame is still transmitted. The rule is the
AnnaBridge 171:3a7713b1edbc 462 * same for rxFifoFullThreshold in the receive direction.
AnnaBridge 171:3a7713b1edbc 463 * 4. When "kENET_ControlFlowControlEnable" is set in the macSpecialConfig, ensure
AnnaBridge 171:3a7713b1edbc 464 * that the pauseDuration, rxFifoEmptyThreshold, and rxFifoStatEmptyThreshold
AnnaBridge 171:3a7713b1edbc 465 * are set for flow control enabled case.
AnnaBridge 171:3a7713b1edbc 466 * 5. When "kENET_ControlStoreAndFwdDisabled" is set in the macSpecialConfig, ensure
AnnaBridge 171:3a7713b1edbc 467 * that the rxFifoFullThreshold and txFifoWatermark are set for store and forward disable.
AnnaBridge 171:3a7713b1edbc 468 * 6. The rxAccelerConfig and txAccelerConfig default setting with 0 - accelerator
AnnaBridge 171:3a7713b1edbc 469 * are disabled. The "enet_tx_accelerator_t" and "enet_rx_accelerator_t" are
AnnaBridge 171:3a7713b1edbc 470 * recommended to be used to enable the transmit and receive accelerator.
AnnaBridge 171:3a7713b1edbc 471 * After the accelerators are enabled, the store and forward feature should be enabled.
AnnaBridge 171:3a7713b1edbc 472 * As a result, kENET_ControlStoreAndFwdDisabled should not be set.
