Level triggering not working on LPC 804 board

Hi,

Currently I am working on LPC804 controller. In that pin interrupt method only working in EDGE triggering. Level triggering method isn't working. I tried the LPCOpen demo code also. Kindly give some reference on this.

Hello @Balaji_KG

How do you test on LPCopen demo? How about change to another pin?

And please check all the related registers configured correctlly.

Alice

Dear @Alice_Yang ,

I checked the demo code through MCU expresso IDE. In that I configured GPIO pin and all registers properly. still, Level triggering not working but edge triggering is working properly.
