I have an external peripheral which is connected to port D3.
I set this port as interruptable.
My problem is that the interrupt is called only on falling edge. The pdf doesn't mention any thing about falling edge only.
This is my init sequence:
|PTDSC_PTDIE = 0;||//first disable interrupt|
|PTDPS_PTDPS3 = 1; //Enable the interrupt pin|
|PTDSC_PTDACK = 1; //Clear any false interrupts|
|PTDSC_PTDIE = 1; //enable interrupts|
|PTDDD_PTDDD3 = 0; //input|
