5.9    Timing Diagrams

The 68000 family of processors (68000, 68008, 68010, and 68012) uses a handshaking mechanism to transfer data between the processors and the peripheral devices. This means that all these processors can transfer data asynchronously to and from peripherals of varying speeds.

Figure 5.15 shows 68000 read and write cycle timing diagrams.
