I am planning to use your can_top.v from http://www.opencores.org/projects/can/ for my project, but it’s very new to me. Please help with these questions.

1. Where does CAN_data connect to Can_top? Can_data is (SOF,ID,RTR,DLC….) I guess it connects to wb_dat_i.Where can I find all addresses for registers?
2. Is ack_o used for both tx and rx when it completed?

Thank you very much.
