Hi, on a PIC24FV, using external oscillator, if I make the whole chip sleep, and I enable an CNxx INT, will the chip wake up after just one cycle? The datasheet seems to concentrate on what happens if you use a crystal (of course it will take ages to wake up), but what if I use an external oscillator? Will it wake up "instantly"?
