* @brief Populated vector table in ROM
|
|
*
|
|
* Vector table at the beginning of the image for starting system. The reset
|
|
* vector is the system entry point, ie. the first instruction executed.
|
|
*
|
|
* The table is populated with all the system exception handlers. The NMI vector
|
|
* must be populated with a valid handler since it can happen at any time. The
|
|
* rest should not be triggered until the kernel is ready to handle them.
