* Cleaned up the uC5282 ISR stuff to make the casts and whatnot more readable. Also made the offsets relative to the VBR (which is at 0x0 for this BSP) to silence a GCC warning. * Refactored the default exception handler to map a struct to the stack instead of taking the address of pc and under-indexing it. The compiler was not particularly happy about the previous implementation.
