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

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.
