I'm using pin 2.9 as an edge, low, interrupt input.
In one function I have to disable it, but that doesn't seem to be working. Even after using GPIOIntDisable( 2, 9); my code still calls the handler when the pin goes low.

The relevant parts:

void PIOINT2_IRQHandler (void)
{
RF_interrupt_handler( );
GPIOIntClear( 2, 9 );//clear interrupt
}

int main(void)
{
GPIOInit( );
GPIOSetDir( 2, 9, 0 );
GPIOSetInterrupt( 2, 9, 0, 0, 0 ); 
GPIOIntEnable( 2, 9 );

...

Then somewhere else I call a function and in the beggining of it goes GPIOIntDisable( 2, 9); and in the end GPIOIntEnable( 2, 9);
Putting a break point in the RF_handler line stops the debugger when the interrupt is supposedly disabled. What am I missing?

Ever tried clearing the int just before disabling it?

Just tried that, and no success.
