MOTOROLA
The program counter value saved in this stack frame is the operation word
address of the coprocessor instruction during which the primitive is received.
The scanPC field contains the value of the MC68030 scanPC when the pri-
The coprocessor uses this primitive to request exception processing for an

mitive is received. If the current instruction does not evaluate an effective
address prior to the exception request primitive, the value of the effective
address field in the stack frame is undefined.
exception during the instruction dialog with the main processor. If the ex-
ception handler does not modify the stack frame, the MC68030 returns from
attempts to continue executing the suspended instruction by reading the
response CIR and processing the primitive it receives.
