Fischer,

I actually works as expects,thanks a lot.

now the instruction

"WRCTL ienable,r2"

works,It can enable IRQ.

the difference between us:

you uses "hello world small" as start,while I use"hello led".

other different like :memory addr,input triger(you use 'fall edge';I 'rise edge' ),and some I think less important set.

all in all.thank you a lot!

Best wishs.
