5.2. Reset Signals

Each of the CPRI PHY Channels in the core has its own set of reset signals. The i_reconfig_reset port is shared.
Table 18.  Reset Signals
Port Name Width (Bits) Domain Description
i_tx_rst_n 1 Asynchronous Resets the selected TX datapath. Active low.
o_tx_rst_ack_n 1 Asynchronous TX datapath reset acknowledgement. Active low.
o_tx_ready 1 Asynchronous TX datapath is out of reset and ready.
i_rx_rst_n 1 Asynchronous Resets the selected RX datapath. Active low.
o_rx_rst_ack_n 1 Asynchronous RX datapath reset acknowledgement. Active low.
o_rx_ready 1 Asynchronous RX datapath is out of reset and ready.
i_reconfig_reset 1 i_reconfig_clk Reconfig reset. Resets the Avalon® memory-mapped interface connections to the F-tile and resets Soft CSR. It does not reset F-tile CSRs. Active high. Must be asserted once upon power-up.
