MOTOROLA MC68000 This chapter describes the basic features of Motorola’s MC68000 (16-bit microprocessor). The addressing modes, instruction set, I/O, and system design concepts of the MC68000 are covered in detail. Motorola’s original MC68000 was designed using HMOS technology. Motorola’s MC68000 is replaced it by a lower power MC68HC000, which is designed using HCMOS technology. The […]
