fx2lp interrupt

hello,

I have interfaced fx2lp with an image sensor,the frame valid is connected to INT1,image sensor is capable of giving 60frames per second.that is 60 times frame valid interrupt per second,is fx2lp is capable of handling 60 interrupts per second?

correct me if i am wrong.

regards,

geetha.

Hello Geethanjali,

When an interrupt occurs, the firmware branches to the ISR. Once the code inside the ISR starts executing, the interrupt is disabled and is enabled again only after the RETI instruction which instructs the return of firmware back to the point of interruption. So, depending on the size of the code that is executed inside the ISR, the number of interrupts that can be processed by FX2LP in a particular time varies.

Best regards,

Srinath S
