Function Documentation

IntDefaultHandler()

static void IntDefaultHandler ( void  )

static

The default interrupt handler.

This is the default interrupt handler for all interrupts. It simply loops forever so that the system state is preserved for observation by a debugger. Since interrupts should be disabled before unregistering the corresponding handler, this should never be called.

Returns

None

__attribute__()

static __attribute__ ( (section(".ramVecs"), aligned(256))  )

static

Global pointer to the (dynamic) interrupt vector table when placed in SRAM.

Interrupt vector table is placed at ".ramVecs" defined in the linker file provided by Texas Instruments.

Note

See interrupt.c for compiler specific implementation!
