Connect up the VSYNC signal to PIO Port B bit #7, the bit that's used for StarNet).
Someone's guessing you're not using StarNet.
Someone will let you have the adventure of setting it up suffice it to say:
An most importantly, remember to reenable interrupts as you exit your ISR.

Someone will let you have the adventure of setting it up suffice it to say:
- Configure the CPU to handle interrupts
- Init the PIO to generate interrupts
- Write the appropriate ISR (Interrupt Service Routine).
- Use the RETI instruction for the PIO
