17.7.7. Stopping and Starting Transmission

Perform the following steps to pause the transmission for some time: †

  1. Disable the transmit DMA (if applicable), by clearing bit 13 (Start or Stop Transmission Command) of Register 6 (Operation Mode Register). †
  2. Wait for any previous frame transmissions to complete. You can check this by reading the appropriate bits of Register 9 (Debug Register). †
  3. Disable the EMAC transmitter and EMAC receiver by clearing Bit 3 (TE) and Bit 2 (RE) in Register 0 (MAC Configuration Register). †
  4. Disable the receive DMA (if applicable), after making sure that the data in the RX FIFO buffer is transferred to the system memory (by reading Register 9 (Debug Register). †
  5. Make sure that both the TX FIFO buffer and RX FIFO buffer are empty. †
  6. To re-start the operation, first start the DMA and then enable the EMAC transmitter and receiver. †
