Hi all,

I have a problem with IT interrupt.

I configure pin PA7/IT4 as falling edg interrupt.

---> ITRFRE = 0x40;

when i get falling edg on pin PA4 the software jump to INT_IT1IT8 interrupt routine

till here evrything fine.

the problem is: if i get another falling edg on PA4 when the software is already in the INT_IT1IT8 interrupt routine the sofware jump again to INT_IT1IT8 after the software get out from the INT_IT1IT8 of the first falling edg.

How can i clear the pending bit of the interrupt???

i tried to disable the interrupt at the beginning of the INT_IT1IT8 and enable it at the end of the INT_IT1IT8, but it didn't help.

Thanks in advance.
