I'm using a UC3C. I need an interrupt each usec with a timer. I am working at 65MHz with PLL, the fastest interrupt I can get is each 2.7usec. The problem is the interrupt routine takes ~120 cycles by itself so I can't get it within a usec. I was looking at the NMI interrupt, is there a way to link the timer interrupt with NMI, instead of using autovector?
Sorry for my English :wink:
