Functions

void setEmacAddr (uint8_t abStationAddr[])
 Set Station MAC address for EMAC module.
Status EMAC_Init (EMAC_CFG_Type *EMAC_ConfigStruct)
 Initializes the EMAC peripheral according to the specified parameters in the EMAC_ConfigStruct.
void EMAC_DeInit (void)
 De-initializes the EMAC peripheral registers to their default reset values.
int32_t EMAC_CheckPHYStatus (uint32_t ulPHYState)
 Check specified PHY status in EMAC peripheral.
int32_t EMAC_SetPHYMode (uint32_t ulPHYMode)
 Set specified PHY mode in EMAC peripheral.
int32_t EMAC_UpdatePHYStatus (void)
 Auto-Configures value for the EMAC configuration register to match with current PHY mode.
void EMAC_SetHashFilter (uint8_t dstMAC_addr[], FunctionalState NewState)
 Enable/Disable hash filter functionality for specified destination MAC address in EMAC module.
int32_t EMAC_CRCCalc (uint8_t frame_no_fcs[], int32_t frame_len)
 Calculates CRC code for number of bytes in the frame.
void EMAC_SetFilterMode (uint32_t ulFilterMode, FunctionalState NewState)
 Enable/Disable Filter mode for each specified type EMAC peripheral.
FlagStatus EMAC_GetWoLStatus (uint32_t ulWoLMode)
 Get status of Wake On LAN Filter for each specified type in EMAC peripheral, clear this status if it is set.
void EMAC_WritePacketBuffer (EMAC_PACKETBUF_Type *pDataStruct)
 Write data to Tx packet data buffer at current index due to TxProduceIndex.
void EMAC_ReadPacketBuffer (EMAC_PACKETBUF_Type *pDataStruct)
 Read data from Rx packet data buffer at current index due to RxConsumeIndex.
void EMAC_StandardIRQHandler (void)
 Standard EMAC IRQ Handler. This sub-routine will check these following interrupt and call the call-back function if they're already installed:
  • Overrun Error interrupt in RX Queue
  • Receive Error interrupt: AlignmentError, RangeError, LengthError, SymbolError, CRCError or NoDescriptor or Overrun
  • RX Finished Process Descriptors interrupt (ProduceIndex == ConsumeIndex)
  • Receive Done interrupt
  • Transmit Under-run interrupt
  • Transmit errors interrupt : LateCollision, ExcessiveCollision and ExcessiveDefer, NoDescriptor or Under-run
  • TX Finished Process Descriptors interrupt (ProduceIndex == ConsumeIndex)
  • Transmit Done interrupt
  • Interrupt triggered by software
  • Interrupt triggered by a Wakeup event detected by the receive filter.

void EMAC_SetupIntCBS (uint32_t ulIntType, EMAC_IntCBSType *pfnIntCb)
 Setup/register Call-back function for each interrupt type in EMAC module.
void EMAC_IntCmd (uint32_t ulIntType, FunctionalState NewState)
 Enable/Disable interrupt for each type in EMAC.
IntStatus EMAC_IntGetStatus (uint32_t ulIntType)
 Check whether if specified interrupt flag is set or not for each interrupt type in EMAC and clear interrupt pending if it is set.
Bool EMAC_CheckReceiveIndex (void)
 Check whether if the current RxConsumeIndex is not equal to the current RxProduceIndex.
Bool EMAC_CheckTransmitIndex (void)
 Check whether if the current TxProduceIndex is not equal to the current RxProduceIndex - 1.
FlagStatus EMAC_CheckReceiveDataStatus (uint32_t ulRxStatType)
 Get current status value of receive data (due to RxConsumeIndex).
uint32_t EMAC_GetReceiveDataSize (void)
 Get size of current Received data in received buffer (due to RxConsumeIndex).
void EMAC_UpdateRxConsumeIndex (void)
 Increase the RxConsumeIndex (after reading the Receive buffer to release the Receive buffer) and wrap-around the index if it reaches the maximum Receive Number.
void EMAC_UpdateTxProduceIndex (void)
 Increase the TxProduceIndex (after writting to the Transmit buffer to enable the Transmit buffer) and wrap-around the index if it reaches the maximum Transmit Number.

Variables

const uint8_t EMAC_clkdiv [] = { 4, 6, 8, 10, 14, 20, 28 }
