AFS TC ISR

Tue Jul 01, 2014 10:47 am

I used TC to set timer for every 1 sec to invoke the TC0_Handler. My question is what happen if my TC0_Handler took .5 sec, the 1st sec my TC0_Handler gets invoked and run then the next invoke is at 2 sec or 2.5 sec?

Thanks,

Are you saying that you are in your ISR for half a second???
