7.2 COPROCESSOR INSTRUCTION TYPES
The M68000 coprocessor interface supports four categories of coprocessor instructions:
general, conditional, context save, and context restore. The category name indicates the
type of operations provided by the coprocessor instructions in the category. The
instruction category also determines the CIR accessed by the MC68020/EC020 to initiate
instruction and communication protocols between the main processor and the
coprocessor necessary for instruction execution.
During the execution of instructions in the general or conditional categories, the
coprocessor uses the set of coprocessor response primitive codes defined for the M68000
coprocessor interface to request services from and indicate status to the main processor.
During the execution of the instructions in the context save and context
