ColdFire processors inhibit sampling for interrupts during the first instruction of all exception handlers.
This allows any handler to effectively disable interrupts, if necessary, by raising the interrupt mask level
contained in the status register.
2.8.1
The exception stack frame is shown in
contains the 16-bit format/vector word (F/V) and the 16-bit status register. The second longword contains
the 32-bit program counter address.
The 16-bit format/vector word contains three unique fields:

+ 0x04
A7→

Format field—This 4-bit field at the top of the system stack is always written with a value of
{4,5,6,7} by the processor indicating a 2-longword frame format. See
records any longword misalignment of the stack pointer that may have existed when the exception
occurred.
Fault status field—The 4-bit field, FS[3–0], at the top of the system stack is defined for access and
address errors along with interrupted debug service routines. See
Numbers
The term ‘fault’ refers to the PC of the instruction that caused the exception. The term ‘next’ refers to the PC
of the instruction that immediately follows the instruction that caused the fault.
