wb_clk_i clk
arst_i reset_n
wb_rst_i export
wb_cyc_i chipselect
wb_stb_i chipselect
wb_ack_o waitrequest_n
wb_try_o export
wb_err_o export
wb_adr_i address
wb_dat_i writedata
wb_dat_o readdata
wb_sel_i byteenable
wb_we_i write
wb_inta_o irq
wb_dma_req_o export
wb_dma_done export
Ignore the warning about using 'chipselect' twice.
The dma signals can be wired directly to a DMA controller.
