Hi,
Â
We are porting the eCos to the embedded
microprocessor MPC823,as everyone know,the most improtant port is the HAL,but I
can not find the syntax rules on how to write the assemble code in HAL.
e.g. What do "I" mean in code:
Â
      asm
volatile ("mfspr %0, %1;" : "=r" (_v_) : "I" (_spr_));
Â
Â
The question is  where I can find
the detailed documents about it.
Thank you in advance.
