Can I register for interrupts on a GPIO pin whose direction is configured as output pin on ADSP-SC5xx ?

I am able to configure GPIO pin as input port and register a interrupt. In this case ISR is called back and things are good.

 

But I want GPIO pin to be output and register an interrupt. When I do this, ISR is not called.

I see that states of the pin are changing(using LED), but ISR is not called.

 

What I read from HRM is that interrupt functionality is completely decoupled from GPIO feature. So in this case it should be programmatically legal to register ISR for output pin and get a callback for ISR when the pin state changes ?
