Hi,

i am working with LPC4370, and i am using two GPIO pin interrupts, Pin_Int0_IRQ and Pin_Int1_IRQ, i have configured them as edge sensitive (rising edge), but the issue is even though i connect the input to ground, it fires an interrupt, continously as long as it is connected. if i leave it floating there is no interrupt.

form the GPIO input pins i tried Pulling them down as well as both pull up and pull down disabled.

can any one point out where i might be going wrong.

Regards,
Suhel

we will have to see the pin setup code and the ISR code. Otherwise you will have to provide a crystal ball we can gaze into.
