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_RMT   1
	Level interrupt with low priority 1.
#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   4
	Level interrupt with low priority 1.
#define	CPU_INUM_USB   8
	Level interrupt with low priority 1.
#define	CPU_INUM_RTT   9
	Level interrupt with low priority 1.
#define	CPU_INUM_SERIAL_JTAG   10
	Level interrupt with low priority 1.
