The following figure shows the user application pausing data transmission during a frame transfer. The application sends 3 n bytes of data and pauses the data flow after the first n bytes. After the first data word, the application deasserts s_axi_tx_tvalid causing the TX to ignore all data on the bus and transmit idle blocks. The pause continues until s_axi_tx_tvalid is asserted.
