What happens if a callback is activated while processing a previous callback?

In my application, I am using both the PPI and two SPORTS. All three use callbacks. What happens if I am in the middle of the PPORT callback processing the input when the callback for one of the SPORTS is activated? Does the PPI callback get interrupted? Is the second callback queued?
