5.4. Resets

Table 47.  Reset Signals
Signal Name Direction Type Description
subsystem_cold_rst_n In Reset

Asynchronous, active-low hard global reset.

Resets the TX MAC, RX MAC, TX PCS, RX PCS, transceivers (transceiver reconfiguration registers and interface), and Ethernet reconfiguration registers.

This reset leads to the de-assertion of the o_tx_lanes_stableand o_rx_pcs_ready output signals.
i_p<n>_tx_rst_n In Reset

Asynchronous, active-low hard reset.

Resets the TX interface, including the TX PCS and TX MAC. This reset leads to the de-assertion of the o_tx_lanes_stable output signal.

i_p<n>_rx_rst_n In Reset

Asynchronous, active-low hard reset.

Resets the RX interface, including the RX PCS and RX MAC. This reset leads to the de-assertion of the o_rx_pcs_ready output signal.

o_p<n>_tx_rst_ack_n Out Reset Acknowledge

Activelow acknowledge signal for i_tx_rst_n.

The user should not de-assert i_tx_rst_n until o_tx_rst_ack_n is asserted.
o_p<n>_rx_rst_ack_n Out Reset Acknowledge

Activelow acknowledge signal for i_rx_rst_n.

The user should not de-assert i_rx_rst_n until o_rx_rst_ack_n is asserted.
subsystem_cold_rst_ack_n Out Reset Acknowledge

Activelow acknowledge signal for subsystem_cold_rst_n.

The user should not de-assert subsystem_cold_rst_n until subsystem_cold_rst_ack_nis asserted.
