Thanks, but the branch instruction only (as far as I understand)
support 24 bits address jump and there is only room for one instruction
in 0xfffffffc. So I tryed to set a jump to 0xffff8000 where there is
some code that store a 32 bits address in the link register before
trying a jump and it didn't work. Can you send me an example please ?
