Sorry! Yes I used '/'. I just missed it.

I thought... But I didn't find any description about this.

I'm trying, but it's not so easy to debug the Au1200 with the BDI3000.
If I want to single step the code, I should set the "Enable single step
mode" flag in the processor's debug CP0 register, and clear when I'm
using breakpoints, and other goodies... :)
