When the MC68030 detects a protocol violation, it does not automatically

processor initiates exception processing using the mid-instruction stack frame
(refer to Figure 10-43) and the coprocessor protocol violation exception vector
number 13. If the exception handler does not modify the stack frame, the
main processor reads the response CIR again following the execution of an
RTE instruction to return from the exception handler. This protocol allows
extensions to the M68000 coprocessor interface to be emulated in software
by a main processor that does not provide hardware support for these ex-
