When the coprocessor requests the transfer of an operand, the main pro-
cessor performs the transfer by reading from or writing to the 32-bit operand

The MC68030 aligns all operands transferred to and from the operand CIR

when accessing the operand CIR.
When the coprocessor requests the transfer of one or more main processor
