66AK2H14: What interrupt gets assert on CPTS time synchonization event when TS_INT_ENABLE is enabled?

I'm using XTCIEVMK2X ver4.0 board and trying to do some experiments with PTP and hardware time stamping. I'd like to attach an ISR handler to do some processing when a CPTS time synchronization event occurs. I've enabled the interrupt in TS_INT_ENABLE but looking through ARM CorePac Interrupts table (in SPRS866G), I'm unable to find which interrupt it corresponds with. Any help would be appreciated.
