Also in following the code style the actual statement would also need to include an IFDEF for multi-channel-config but maybe not necessary for you test locally?
So Mementary Turbo 3H work for you? If you don't own multi channel, MT should be 3H from ON. I think l423 be identical for simple or multi channel.
I can't find where arg should be equals to 0... steady_state always call with arg <> 0
