Hello I'm using the config tools to set up the SCT and I am having troble getting the IRQ to generate, even thou the counter is running and going passed the match value.

if ((SCT0->EVFLAG & 1) == 1) //event 0 pending //1.5uS elapsed

SCT0->EVFLAG &= ~1; //Clear the SCT Event 0 Interrupt

Thanks Alice,
I can only see an IRQ for the SCT as a whole NVIC #12, where are the event IRQ held?
The only other place I can see to set this up is STATEMASKn, and this is already set up correctly.
