4.5.11. Configuration Slave (cs_lite_respndr) - RP Only

The Configuration Slave (CS) interface is applicable only in Root Port mode. For functional description, refer to Configuration Slave (CS) (14-bit address format) in the Multi Channel DMA Intel FPGA IP for PCI Express User Guide. Note: The AVMM interface is replaced with AXI Lite.

Interface clock: axi_lite_clk
