C++ (Cpp) GMAC_MAN_WTN Examples

Example #1

File: samv71_eth.c Project: frankzzcn/M2_SE_RTOS_Project

void samv71EthWritePhyReg(uint8_t phyAddr, uint8_t regAddr, uint16_t data)
{
   //Set up a write operation
   uint32_t value = GMAC_MAN_CLTTO | GMAC_MAN_OP(1) | GMAC_MAN_WTN(2);
   //PHY address
   value |= GMAC_MAN_PHYA(phyAddr);
   //Register address
   value |= GMAC_MAN_REGA(regAddr);
   //Register value
   value |= GMAC_MAN_DATA(data);

   //Start a write operation
   GMAC->GMAC_MAN = value;
   //Wait for the write to complete
   while(!(GMAC->GMAC_NSR & GMAC_NSR_IDLE));
}

Example #2

File: samv71_eth.c Project: frankzzcn/M2_SE_RTOS_Project

uint16_t samv71EthReadPhyReg(uint8_t phyAddr, uint8_t regAddr)
{
   //Set up a read operation

   //Start a read operation
   GMAC->GMAC_MAN = value;
   //Wait for the read to complete
   while(!(GMAC->GMAC_NSR & GMAC_NSR_IDLE));

   //Return PHY register contents
