All ColdFire processors inhibit interrupt sampling during the first instruction of all exception handlers.
This allows any handler to disable interrupts effectively, if necessary, by raising the interrupt mask level
contained in the status register. In addition, the ISA_A+ architecture includes an instruction (STLDSR)
that stores the current interrupt mask level and loads a value into the SR. This instruction is specifically
intended for use as the first instruction of an interrupt service routine that services multiple interrupt
requests with different interrupt levels. For more details, see ColdFire Family Programmer’s Reference
Manual.

A 4-bit format field at the top of the system stack is always written with a value of 4, 5, 6, or 7 by
the processor, indicating a two-longword frame format. See
There is a 4-bit fault status field, FS[3:0], at the top of the system stack. This field is defined for
access and address errors only and written as zeros for all other exceptions. See

Fault refers to the PC of the instruction that caused the exception. Next refers to the PC
of the instruction that follows the instruction that caused the fault.
