This link

http://www.nongnu.org/avr-libc/user-manual/

has documentation for the avr libc. There is a section describing how to
declare and use ISR's including definitions of the different vectors.

I was looking in the RC input files and found

ISR( RCI_CAPT_vect )

{


is this where the program goes when the capture happens?
How does this work? I am used to something like

void interrupt org 0x16 { //org sets the location in the ROM to 0x16

Thanks,
Justin
