I have started with conbus. According to the protocol (b3 wishbone), master keeps
data on dat_o and slave latches the same to its dat_o (write) and
vice-versa for dat_i (read).

However, in the wb_conbus_top.v file written, I found that
m0_dat_o=s0_dat_i (line-388 eventually takes that). I couldn't figure out
why this kind of assignment is happening, which is against the b3 wishbone
protocol.

Can someone please explain me on this. (Attached the code)
