The exception stack frame is shown in
the 16-bit format/vector word (F/V) and the 16-bit status register, and the second longword contains the
32-bit program counter address.
The 16-bit format/vector word contains 3 unique fields:
3-8
“Fault” refers to the PC of the instruction that caused the exception.
“Next” refers to the PC of the next instruction that follows the instruction that caused the fault.
