LPC1347- clearing level sensitive level interrupt

[mateuszkiełbasa]

I'm using LPC1347 board which has two group interrupts. I'd like to write simple program which uses only one pin group interrupt (for testing only). Edge interrupts works well but when I change interrupt type to low level sensitive (or / and - it doesn't matter) I can't clear interrupt status so the program is stucked in the ISR... Writing one to CTRL register has not any effect. Is different way of clearing level group interrupts?

Hi Mateusz Kiełbasa,

Thank you for your interest in NXP Semiconductor products and 

for the opportunity to serve you.

I was wondering if you can share a build-able demo with me, then I can replicate the phenomenon on my site.

I'm looking forward to your reply.

TIC
