How to clear PLL interrupt bit on ADuC702x?

What is the recommended way to clear the PLL (lock lost) interrupt bit on a ADuC702x?

 

On a related note, the data sheet says "In case of crystal loss, the watchdog timer should be used. During initialization, a test on the RSTSTA register can determine if the reset came from the watchdog timer.". Is there any way to tell if the watchdog timer reset was caused by a loss of external crystal as opposed to any other cause?
