Lpc2000

Hello All!
	I'm trying to write a simple interrupt routine for a external interrupt 
source (EINT0) for a LPC2106. As there's no selection between level or 
edge-triggered interrupts, I want to to wait until there's a logic 1 on the 
EINTx pin to clear the intrrupt on the VIC to not count a long strobe as 
several different interrupts. This goes along with the LPC2106 user's manual, 
as on page 40 it says that to clear a pending intrerrupt on EINTx I have to 
wait until there's a high level on the pin, so I REALLY want to wait until a 
logic 1 is present. But how do I do that?
	I already tried a code like this in my interrupt handler:

(defines based on freeRTOS)

	while( (GPIO0_IOPIN & (0x01<<16)) == 0 );
	SCB_EXTINT |= 0x01;
	VICVectAddr = serCLEAR_VIC_INTERRUPT;

	If I remove the while() loop; I get several interrupts, as expected. But if I 
leave the loop, after the first strobe on the pin, the processor gets stuck. 
Can I use the IOPIN register to read the current logic level on the pin? I 
think so, by reading the register description on page 81 of the UM.

Thanks a lot
