How to disable IRQ7?

Hi,

 

I read that IRQ7 can't be masked in MQX because of priority (level 7). I tried to use this IRQ7 but it didn't work properly.

Now, I want to disable the IRQ7 and use this pin as GPIO.

 

I wrote in bsp_init.c:

 

mcf5225_init()

{

....

reg_ptr->GPIO.PNQPAR = 0x1555; //Disable IRQ7

....

}

 

But nothing was changed. When I change the pin value, the MQX hangs (seems that execute "spurious interrupt")

Any idea?
