CPU interrupt numbers
All interrupts that are used for RIOT-OS are preallocated and fix. The allocated interrupts are all level interrupts, most of them with low priority.
#define	CPU_INUM_GPIO   2
	Level interrupt with low priority 1.
#define	CPU_INUM_CAN   3
	Level interrupt with low priority 1.
#define	CPU_INUM_UART   5
	Level interrupt with low priority 1.
#define	CPU_INUM_RTC   9
	Level interrupt with low priority 1.
#define	CPU_INUM_I2C   12
	Level interrupt with low priority 1.
#define	CPU_INUM_WDT   13
	Level interrupt with low priority 1.
#define	CPU_INUM_SOFTWARE   17
	Level interrupt with low priority 1.
#define	CPU_INUM_ETH   18
	Level interrupt with low priority 1.
#define	CPU_INUM_TIMER   19
