2.8. PMA Avalon Memory-Mapped Signals
The following table describes the PMA Avalon® memory-mapped signals that are a part of the F-Tile PMA/FEC Direct PHY Multirate Intel FPGA IP.
Signal Name | Clocks Domain/Resets | Direction | Description |
---|---|---|---|
reconfig_xcvr_clk | N/A | Input | Reconfiguration Interface Clock |
reconfig_xcvr_reset | reconfig_xcvr_clk | Input | PMA reconfiguration interface reset. You must assert this reset at least once after power on. |
reconfig_xcvr_address[17+K p:0] | reconfig_xcvr_clk | Input | Reconfiguration Interface Address K p=Ceiling(log2(N)). Upper address bits are for shared PMA decoding if more than one PMA exists. |
reconfig_xcvr_byteenable[3:0] | reconfig_xcvr_clk | Input | Byte Enable. If byteenable[3:0] is 4’b1111, uses 32-bit Dword Access; otherwise uses byte access. |
reconfig_xcvr_write | reconfig_xcvr_clk | Input | Reconfiguration Write |
reconfig_xcvr_read | reconfig_xcvr_clk | Input | Reconfiguration Read |
reconfig_xcvr_writedata[31:0] | reconfig_xcvr_clk | Input | Reconfiguration Write data |
reconfig_xcvr_readdata[31:0] | reconfig_xcvr_clk | Output | Reconfiguration Read data |
reconfig_xcvr_waitrequest | reconfig_xcvr_clk | Output | Reconfiguration Wait Request |
reconfig_xcvr_readdatavalid | reconfig_xcvr_clk | Output | Reconfiguration Read Data Valid. Optional port, available if the port is enabled in parameter editor. |
