1. Assert the below signals:
ctl_rx_enable = 1’b1
ctl_tx_send_rfi = 1’b1
2. Wait for RX_aligned then deassert / assert the below signals:
ctl_tx_send_rfi = 1’b0
ctl_tx_enable = 1’b1
3. When TX/RX flow control is enabled in the Vivado IDE (the default setting), assign the signals below.
Note: If you have disabled TX/RX flow control in the Vivado IDE, skip to step 4 .
ctl_tx_pause_req[8:0] = 9’b100
ctl_rx_pause_enable[8:0] = 9’b1FF
ctl_tx_pause_enable[8:0] = 9’b1FF
ctl_tx_pause_quanta8[15:0] = 16’bFFFF
ctl_tx_pause_refresh_timer8[15:0] = 16’bFFFF
