When fast interrupt is triggered by ADC , I find that it enter fast interrupt only once .

for example :

Over the ACOMP_X_THRESH , the fast interrupt is triggered by ADC once .

If over the ACOMP_X_THRESH , Can the fast be triggered all the time ?

I'm pretty sure that it is edge sensitive, meaning that it will only get triggered once, assuming it stays high. You can check the raw data in another register to see if it has gone down yet.
