DESCRIPTION
|
|
Vector table in ROM 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.
