Table 76.  PHY Reconfiguration Interface Signals
Signal Name Direction EP/RP/BP Clock Domain Description
xcvr_reconfig_readdata[7:0] Output EP/RP/BP xcvr_reconfig_clk Avalon-MM read data outputs
xcvr_reconfig_readdatavalid Output EP/RP/BP xcvr_reconfig_clk Avalon-MM read data valid. When asserted, the data on xcvr_reconfig_readdata[7:0] is valid.
xcvr_reconfig_write Input EP/RP/BP xcvr_reconfig_clk Avalon-MM write enable
xcvr_reconfig_read Input EP/RP/BP xcvr_reconfig_clk Avalon-MM read enable
xcvr_reconfig_address[24:0] Input EP/RP/BP xcvr_reconfig_clk

Avalon-MM address bit[24:21] are used to indicate channel number.

xcvr_reconfig_writedata[7:0] Input EP/RP/BP xcvr_reconfig_clk Avalon-MM write data inputs
xcvr_reconfig_waitrequest Output EP/RP/BP xcvr_reconfig_clk When asserted, this signal indicates that the PHY is not ready to respond to a request.
