How can I utilize different interrupts?

Nick Gammon wrote an small primer on Atmega interrupts: here

He listed 26 interrupts and I was wondering if they could be accessed and used in my code i.e., what functions do I call with what parameters?

You can use any of the interrupts by creating a function using the interrupt vector name - for example

ISR (SPI_STC_vect) {

}

(The example from Nick's page)

Note that some of the interrupts are already used by the Arduino system

Time to read the Atmega328 data sheet PDF.
