Interrupt API
➲ The Avr C-library provides default interrupt
routines, which get used unless overridden
➲ If you wish to provide an interrupt routine for
a particular signal you must, in addition to
any required AVR setup, create the function
using one of the SIGNAL() or INTERRUPT()
macros, along with the appropriate signal
names
