3.4.3. Reset Signals
|Signal Name||Clocks Domains||Direction||Description|
|tx_reset||asynchronous||input||TX reset input for TX PMA and TX datapath. Must asserted until tx_reset_ack is asserted.|
|rx_reset||asynchronous||input||RX reset input for RX PMA and RX datapath. Must be kept asserted until rx_reset_ack is asserted.|
|tx_reset_ack||asynchronous||output||TX fully in reset indicator.|
|rx_reset_ack||asynchronous||output||RX fully in reset indicator.|
|tx_am_gen_start||asynchronous||output||When using FEC, indicates when to start sending alignment markers. This clears once tx_am_gen_2x_ack is asserted.|
|tx_am_gen_2x_ack||asynchronous||input||When using FEC, indicates to the reset sequencer at least 2 alignment markers were sent since tx_am_gen_start is asserted. This signal is deasserted after tx_am_gen_start is deasserted.|
|tx_ready||asynchronous||output||Status port to indicate when TX PMA and TX datapath are reset successfully and ready for data transfer.|
If RX de-skew is disabled:
Status port to indicate when RX PMA and RX datapath are reset successfully and ready for data transfer.
If RX de-skew is enabled:
Status port to indicate when RX PMA and RX datapath are reset successfully, RX de-skew is done, and ready for data transfer.
