2.9. Datapath Avalon Memory-Mapped Signals
The following table describes the Datapath Avalon® memory-mapped signals that are a part of the F-Tile PMA/FEC Direct PHY Multi-Rate Intel FPGA IP.
Signal Name | Clocks Domain/Resets | Direction | Description |
---|---|---|---|
reconfig_pdp_clk | N/A | Input | Reconfig Interface Clock |
reconfig_pdp_reset | reconfig_pdp_clk | Input | Reconfiguration Interface Reset |
reconfig_pdp_address[13+K d :0] | reconfig_pdp_clk | Input | Reconfig Interface Address. K d=Ceiling(log2(N)). Word address. EMIB core adapter and soft CSR registers use unused space of F-tile Datapath Avalon® memory mapped 16-bit address. |
reconfig_pdp_byteenable [3:0] | reconfig_pdp_clk | Input | Byte Enable. If byteenable[3:0] is 4’b1111, 32-bit Dword Access is assumed; otherwise byte access is used. |
reconfig_pdp_write | reconfig_pdp_clk | Input | Reconfig Write |
reconfig_pdp_read | reconfig_pdp_clk | Input | Reconfig Read |
reconfig_pdp_writedata [31:0] | reconfig_pdp_clk | Input | Reconfig Write data |
reconfig_pdp_readdata [31:0] | reconfig_pdp_clk | Output | Reconfig Read data |
reconfig_pdp_waitrequest | reconfig_pdp_clk | Output | Reconfig Wait Request |
reconfig_pdp_readdatavalid | reconfig_pdp_clk | Output | Reconfig Read Data Valid. Optional port, available if the port is enabled in parameter editor. |
