Hi All,

I have a query regarding the usage of capture input
pin in TMS320F2808. The question is as follows

1. I've configured Capture Input 1 to trigger an
interrupt on any one of the four capture events
(CEVT1-CEVT4).

2. The polarity of the event (Rising Edge, RE or
Falling Edge, FE) is also configurable by writing to
the capture control register ECCTL1. I've configured
CEVT1 & CEVT3 as RE & CEVT2 & CEVT4 as FE.

3. In the capture ISR, I'm toggling a GPIO pin of the
processor to verify the servicing of the interrupt.

When I run my code, I always observe that the capture
interrupt is not serviced in the FALLING EDGE even
though all settings are right. Rising edge detection
works fine. 

If anyone of you have come across this issue & solved
it, please help me out.

Thanks,
Vishal
