 Initialize architecture specific interrupt handling.
 

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_RTT   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
 Level interrupt with medium priority 2.
 
#define CPU_INUM_FRC2   20
 Level interrupt with medium priority 2.
 
#define CPU_INUM_SYSTIMER   20
