The distinction between standard peripheral hardware and a M68000 copro-
cessor is important from a perspective of the programming model. The pro-
gramming model of the main processor consists of the instruction set, register
set, and memory map available to the programmer. An M68000 coprocessor
gramming model for a coprocessor is different than that for a peripheral
device. A coprocessor adds additional instructions and generally additional
