7.1. Status Interface
In non-FEC and Firecode FEC variant, asserted when the IP core completes 66-bit block boundary alignment on all PCS lanes.
Otherwise, asserted when the IP core completes the codeword alignment on all FEC lanes.
|o_rx_am_lock||Asserted when the RX PCS completes detection of alignment markers and deskew of the PCS lanes.
Not supported for 10G/25G variants.
|o_local_fault_status||Asserted when the RX MAC detects a local fault: the RX PCS detected a problem that prevents it from receiving data. This signal is functional only if you set the Client Interface parameter to the value of MAC segmented or MAC Avalon ST in the parameter editor.|
|o_remote_fault_status||Asserted when the RX MAC detects a remote fault: the remote link partner sent remote fault ordered sets indicating that it is unable to receive data. This signal is functional only if you set the Client Interface parameter to the value of MAC segmented or MAC Avalon ST in the parameter editor.|
|i_stats_snapshot||Directs the IP core to record a snapshot of the current state of the statistics registers. Assert this signal to perform the function of both the TX and RX statistics register shadow request fields at the same time, or to perform that function for multiple instances of the IP core simultaneously.
This signal is synchronous with the i_clk_tx clock.
|o_rx_hi_ber||Asserted to indicate the RX PCS is in a HI BER state according to Figure 82-15 in the IEEE 802.3-2015 Standard. The IP core uses this signal in auto negotiation and link training.|
|o_rx_pcs_fully_aligned||Asserts when RX PCS is ready to receive data.|
