ADSP-21369 FLAG3 as interrupt

Hi,

As the title says, I'm trying to define the FLAG3 pin as an interrupt, but I don't see how. In the schematic files of the EZ-KIT Lite it says that this pin is IRQ3, but in the hardware reference document it only mentions IRQ0-2. Is there any way I can use this pin as an interrupt?

Thanks,

Luis
