[beking]

hi,everyone.
now ,in my SoC project,the whole HDL code have been done successful.
...
our control system has no RTOS,so many many assemble language.
and when i use the instruction that is"l.sfges"...
and then i use "l.sfne...",please tell me the FLAG (SR[F])must remove between these two instructions~~
if not,please tell me how i do ?
